In dieser spannenden Episode des Bauherren Podcasts Schweiz tauchen wir tief in ein Thema ein, das viele unterschätzen – den Vorsorgeauftrag und die Zusammenarbeit mit der KESB (Kindes- und Erwachsenenschutzbehörde). Unser Gast Jürg Gyr, Geschäftsführer der Neutrale Finanzdienstleistung GmbH, bringt nicht nur juristische Expertise mit, sondern auch jahrelange Erfahrung im direkten Umgang mit der KESB. Er zeigt auf, wie man einen Vorsorgeauftrag korrekt erstellt, welche Fehler häufig passieren und wie man Konfliktpotenziale mit der KESB im Vorfeld entschärfen kann. Besonders wertvoll: Jürg's praxisnahe Einblicke darin, wie man die KESB nicht als Gegner, sondern als Partner verstehen kann – vorausgesetzt, man weiß, wie man mit ihr spricht. Für alle Bauherren, Unternehmer, Investoren und Familienmenschen ein äußerst relevantes Thema, das im Ernstfall über Wohl oder Chaos entscheiden kann. Diese Episode ist ein Muss für alle, die vorausschauend denken, Verantwortung übernehmen und ihre Familie und ihr Lebenswerk schützen wollen. Lass dir deinen Vorsorgeauftrag von Jürg erstellen.

Was passiert, wenn du plötzlich nicht mehr urteilsfähig bist – sei es durch Krankheit oder Unfall – und niemand weiß, was zu tun ist? In dieser besonderen Episode des Bauherren Podcast Schweiz sprechen wir mit Jürg Gyr, einem erfahrenen Vorsorgeauftrag-Experten, über ein Thema, das zwar selten im Rampenlicht steht, aber für jeden von uns – besonders für Immobilienbesitzer, Unternehmer und Familienväter – von zentraler Bedeutung ist: der Vorsorgeauftrag. Wir beleuchten, warum ein fehlender oder unklar formulierter Vorsorgeauftrag fatale Konsequenzen haben kann und warum die KESB (Kindes- und Erwachsenenschutzbehörde) dann das Zepter übernimmt. Jürg teilt mit uns praktische Beispiele aus seiner Erfahrung, erläutert die grössten Fehler bei Online-Vorlagen und gibt einen klaren 4-Schritte-Plan, wie du deinen eigenen Vorsorgeauftrag korrekt und rechtssicher erstellen lässt – insbesondere, wenn Immobilien oder ein Unternehmen im Spiel sind. Diese Episode ist ein Muss für alle, die vorausschauend denken, Verantwortung übernehmen und ihre Familie und ihr Lebenswerk schützen wollen. Lass dir dein Vorsorgeauftrag von Jürg erstellen.

Misschien moet ik eens ophouden met die "click bait" titels, nietwaar? Maar hoe dat ook zij, een recente waarneming schudt ons begrip van de evolutie van het heelal weer eens flink door de war.

Laugardagur 29. mars Helgi-spjall: Gyrðir Elíasson Gyrðir Elíasson, rithöfundur, skáld, myndlistarmaður og þýðandi ræðir um líf sitt og köllun í skáldskap og listum en líka í einmanaleika og jaðartilvist, um vináttutengslin við textann og náttúruna.
,,Ég treysti sjálfri mér og hef trú á þessu tæki sem listmeðferðin er. Hún er tæki til að tjá tilfinningar sínar og vinna með og losa sig við erfiðar tilfinningar. Myndsköpunin er þá notuð til að vinna með sig persónulega og til að þroskast í gegnum." - er meðal þess sem haft er eftir myndlistarkonunni og listþerapistanum Sigríði Björnsdóttur í bók þeirra Ágústu Oddsdóttur og Egils Sæbjörnssonar um ævistarf Sigríðar, Art can Heal. Á fimmtudag verður blásið til málþings um listmeðferð til heiðurs Sigríði, á vegum Listasafns Íslands og Myndlistarmiðstöðvar. Þau Ágústa og Egill koma við í hljóðstofu og segja okkur frá eiginleikum listmeðferðar og starfi Sigríðar. Við fáum líka pistil frá Gauta Kristmannssyni, sem að þessu sinni fjallar um ljóðasafn norska stórskáldsins Olav Hauge, Undir eplatrénu. Ljóðasafnið er að mestu fengið úr síðustu þremur bókum Hauges en Gyrðir Elíasson íslenskaði og ritaði formála. Við höldum líka áfram umfjöllun um kvikmyndaleikstjórann David Lynch. Lynch málaði heiminn í sterkum, dulúðugum og súrrealískum litum, sem virðast á stundum koma úr annari vídd, og bjó til andrúmsloft sem hefur einfaldlega verið kallað lynchían. Við ætlum að velta þessari lynchian tilfinningu fyrir okkur í þætti dagsins með Rúnari Rúnarssyni kvikmyndaleikstjóra, Ásgrími Sverrissyni kvikmyndagerðamanni, Hrönn Sveinsdóttur framkvæmdastýru bíó paradís og Evu Rún Snorradóttur rithöfundi og sviðslistakonu.

Maximize the "document section" in your programming platform if it includes one. I no longer use True Coach in my biz, but when I did, I was the Document section QUEEN. Ideas: All policies and communication guidelines uploaded into doc section block/cycle/season breakdowns mini e-books embedded videos into PDFs how to record your own form checks how to do your own form checks ancillary programs/movements like "desk mobility" or "movement snacks" that maybe don't 'go' inside the regularly scheduled program nutrition guides mindset guides body image guides More ideas: Include journal/reflection prompts throughout your program Include videos beyond movement/exercise; upload talking head videos/mini trainings directly into the program based on that block's theme, etc. Use emoji's or create a framework (mine was GYR system before we moved to Animal Architypes for Seasons lol) to help guide clients' overall output/intensity for the day Create an entire program that's not fitness related and schedule out just like a regular program. You can totally use the software you have to deliver a mini-course or something like it. Happy iterating!
Í þættinum heyrum við af nýrri plötu og útgáfutónleikum flautuseptettsins Viibru, en stallsysturnar sjö sem sveitina skipa ferðuðust víða um heim með Björk Guðmundsdóttur á síðustu árum, blésu í fjölbreyttar flautur sínar og runnu í raun nánast saman við tónlistina. Við hittum í þættinum Berglindi Maríu Tómasdóttur, flautuleikara og Margréti Bjarnadóttur, danshöfund, og ræðum tónleika í Hörpu á sunnudag, nýju plötuna og samstarfið við Björk.

The United States will soon get a new freighter operator when Miami-based 7Air Cargo gains certification.The startup airline has agreed to lease two 2006-vintage 737-800SFs from Aircastle as its first freighters. The first of those (34799, ex-SpiceJet) finished receiving its new paint job in Goodyear, Ariz., (GYR) this week.7Air Cargo expects to start flying proving runs in March and hopes to obtain its AOC in April.“We're on track as of today,” Chief Executive Amos Rodriguez says in this week's episode of the “Cargo Facts Connect” podcast.7Air is part of Xtreme Holdings and is in discussions with cargo customers. It will not only operate charters but will also move its own freight, Rodriguez said.With the first two 737-800SFs secured, 7Air is considering adding more 737-800 freighters and is even looking at widebodies.“As far as the first route, we are concentrating on Central America,” Vice President of Commercial Operations Carlos Cock says. “There'll be several destinations within Central America.”Tune in to this week's podcast to hear more on 7Air Cargo's plans as Rodriguez and Cock speak with Cargo Facts Editor Jeff Lee.
All of This is Chance nefnist plata úr smiðju írska tónlistarmannsins Lisu O'Neill, en hún kom út í fyrra og vakti þónokkra athygli. Á plötunni sækir Lisa í írska þjóðlagatónlist og miðlar textum um móðurástina, hina kvenlægu orku, föglasöng og hina vægðarlausu raun sem liggur að baki allra tákna. Við kynnum okkur þessa mögnuðu plötu í þætti dagsins. Soffía Auður Birgisdóttir, bókmenntafræðingur, verður einnig með okkur í þættinum og að þessu sinni hugar hún að bókunum Dulstirni og Meðan glerið sefur sem Gyrðir Elíasson sendi frá sér fyrir jól. Við lítum líka inn á sýninginuna Hendi næst í Ásmundasafni, þar sem verk samtímalistamanna sem skapa myndverk með eigin höndum og nýta handverkshefðir, eiga í samtali við verk Ásmundar. Við hittum Becky Foresythe, sýningarstjóra, og tökum hana tali um sýninguna í þættinum. Umsjón: Halla Harðardóttir og Tómas Ævar Ólafsson

In this episode, hosts Kevin Palmieri and Alan Lazaros examine how the choices we make, and the path we take have a more significant impact on our journey than the speed at which we travel. By focusing on the direction we want to go, we can ensure that our efforts are aligned with our goals and values. Through thought-provoking examples, they highlight the importance of engaging in activities that add value and contribute positively to our lives and those around us. They emphasize the power of constructive actions in shaping our personal growth and our impact on the world. They discuss how things change over time, primarily as we pursue a particular endeavor.

Á fræðslufundi ADHD samtakanna í síðustu viku var yfirskriftin ADHD og náin sambönd og var athyglinni beint að pörum þar sem annar aðilinn er með ADHD en hinn ekki. Á fundinum töluðu Anna Elísa Gunnarsdóttir félagsráðgjafi og eiginmaður hennar Arnór Heiðarsson aðstoðarskólastjóri. Þau deildu reynslu sinni af ADHD í þeirra sambandi, hverjar helstu áskoranirnar, í samskiptum og verkaskiptingu heimilisins, eru og hvernig hægt er að takast á við þær áskoranir. Þau hjónin komu í þáttinn í dag. Svo fengum við vinkil frá Guðjóni Helga Ólafssyni, skúffuskáldi og þjóðfræðiáhugamanni úr Flóanum. Í þetta sinn bar Guðjón vinkilinn að örlögum Beothuk þjóðarinnar í Austur- Kanada. Lesandi vikunnar í þetta sinn var Ragnhildur Vigfúsdóttir markþjálfi og fyrrverandi ritstjóri tímaritsins Veru. Við fengum að vita hvaða bækur hún hefur verið að lesa undanfarið og hvaða bækur og höfundar hafa haft mest áhrif á hana í gegnum tíðina. Ragnhildur sagði frá eftirfarandi bókum og höfundum: Pensilskrift e. Gyrði Elíasson Ósýnilegar konur e. Caroline Criado Perez Hamingjugildran e. Hugrún Sigurjónsdóttir Heimurinn eins og hann er e.

Warum Thomas Funk, Portfolio-Manager des GAM Swiss Small & Mid Cap Equity-Fonds, so bullish für „bärenstarke Schweizer Aktien“ ist? In erster Linie, weil viele kleinere Schweizer Medizinstechnik- und Industrie-Spezialisten extrem wettbewerbsfähig sind. Dazu hab sie die Schweizer Franken-Aufwertungswellen 2010 bis 2011, 2014 und zuletzt 2022 aufgrund der Inflationsdifferenzen gezwungen. Da wären wir auch beim zweiten Punkt, der für Schweizer Titel spricht: während die Inflationsrate Im Vorjahr in Österreich und Deutschland bei 8,5 beziehungsweise 8,7 Prozent lag betrug sie in der Schweiz gerade einmal 2,8 Prozent. Deshalb sind auch in der Schweiz die Löhne nicht so stark gestiegen, was die ohnedies hohe Wettbewerbsfähigkeit Schweizer Unternehmen und deren Gewinnmargen noch verbessert. Beim Podcast GELDMEISTERIN zu Gast nennt er beispielsweise Interroll als Hidden Champion, der Transport- und Rollsysteme für Logistiker wie Amazon und DHL produziert. Eine Schweizer Industrieperle sei auch der Zahntechniker Straumann Holding, der in den letzten sechs Monaten rund 50 Prozent zulegte. Seit Börsengang im Juli 1998 hat das Medizintechnik-Unternehmen nahezu sagenhafte 6900 Prozent zugelegt. Wobei man natürlich bei Small- und Midcaps auch bei bärenstarken Aktien stärkere Kursschwankungen aushalten muss und auch einen langen Atem braucht. Der Kurs der Straumann-Aktie hat sich etwa von 2002 bis 2012 kaum vom Fleck bewegt. Thomas Funk hat in seinem Schweizer Small- und Midcap-Fonds Straumann am stärksten gewichtet, vor Lindt & Sprüngli, dem Labortechnik-Hersteller Tecan-Group und dem Vakuumventile-Hersteller VAT Group. Weitere Schwergewichte im GAM Swiss Small & Mid Cap Equity-Fonds: Barry Callebaut AG, einer der weltgrößten Schokoladenfabrikanten, Burkhart Compression Holding, die Immobilienholding DKSH Holding, das Spezialtransportunternehmen Georg Fischer, das Heizungstechnik-und Klimatechnikunternehmen Belimo Holding sowie der Energiemanagementspezialist Landis&Gyr. Mehr zu den bärenstarken Schweizer Aktien in der aktuellen Folge der GELDMEISTEIRN. Viel Hörvergnügen wünscht Podcasthost Julia Kistner.

Nitrogen as a Tracer of Giant Planet Formation II : Comprehensive Study of Nitrogen Photochemistry and Implications for Observing NH3 and HCN in Transmission and Emission Spectra by Kazumasa Ohno et al. on Wednesday 30 November Atmospheric nitrogen may provide important constraints on giant planet formation. Following our semi-analytical work (Ohno & Fortney 2022), we further pursue the relation between observable NH3 and an atmosphere's bulk nitrogen abundance by applying the photochemical kinetics model VULCAN across planetary equilibrium temperature, mass, age, eddy diffusion coefficient, atmospheric composition, and stellar spectral type. We confirm that the quenched NH3 abundance coincides with the bulk nitrogen abundance only at sub-Jupiter mass (< 1MJ) planets and old ages (> 1 Gyr) for solar composition atmospheres, highlighting important caveats for inferring atmospheric nitrogen abundances. Our semi-analytical model reproduces the quenched NH3 abundance computed by VULCAN and thus helps to infer the bulk nitrogen abundance from a retrieved NH3 abundance. By computing transmission and emission spectra, we predict that the equilibrium temperature range of 400--1000 K is optimal for detecting NH3 because NH3 depletion by thermochemistry and photochemistry is significant at hotter planets whereas entire spectral features become weak at colder planets. For Jupiter-mass planets around Sun-like stars in this temperature range, NH3 leaves observable signatures of $sim$ 50 ppm at 1.5, 2.1, and 11 $rm {mu}m$ in transmission spectra and > 300--100 ppm at 6 $rm {mu}m$ and 11 $rm {mu}m$ in emission spectra. The photodissociation of NH3 leads HCN to replace NH3 at low pressures. However, the low HCN column densities lead to much weaker absorption features than for NH3. The NH3 features are readily accessible to JWST observations to constrain atmospheric nitrogen abundances, which may open a new avenue to understand the formation processes of giant exoplanets. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16877v1
NICMOS Kernel-Phase Interferometry II: Demographics of Nearby Brown Dwarfs by Samuel M. Factor et al. on Wednesday 30 November Star formation theories have struggled to reproduce binary brown dwarf population demographics (frequency, separation, mass-ratio). Kernel-phase interferometry is sensitive to companions at separations inaccessible to classical imaging, enabling tests of formation at new physical scales below the hydrogen burning limit. We analyze the detections and sensitivity limits from our previous kernel-phase analysis of archival HST/NICMOS surveys of field brown dwarfs. After estimating physical properties of the 105 late M to T dwarfs using Gaia distances and evolutionary models, we use a Bayesian framework to compare these results to a model companion population defined by log-normal separation and power-law mass-ratio distributions. When correcting for Malmquist bias, we find a companion fraction of $F=0.11^{+0.04}_{-0.03}$ and a separation distribution centered at $rho=2.2^{+1.2}_{-1.0}$ au, smaller and tighter than seen in previous studies. We also find a mass-ratio power-law index which strongly favors equal-mass systems: $gamma=4.0^{+1.7}_{-1.5}-11^{+4}_{-3}$ depending on the assumed age of the field population ($0.9-3.1$ Gyr). We attribute the change in values to our use of kernel-phase interferometry which enables us to resolve the peak of the semimajor axis distribution with significant sensitivity to low-mass companions. We confirm the previously-seen trends of decreasing binary fraction with decreasing mass and a strong preference for tight and equal-mass systems in the field-age sub-stellar regime; only $0.9^{+1.1}_{-0.6}$ % of systems are wider than 20 au and $
Making hot Jupiters in stellar clusters: the importance of binary exchange by Daohai Li et al. on Wednesday 30 November It has been suggested that the occurrence rate of hot Jupiters (HJs) in open clusters might reach several per cent, significantly higher than that of the field ($sim$ a per cent). In a stellar cluster, when a planetary system scatters with a stellar binary, it may acquire a companion star which may excite large amplitude von Zeipel-Lidov-Kozai oscillations in the planet's orbital eccentricity, triggering high-eccentricity migration and the formation of an HJ. We quantify the efficiency of this mechanism by modelling the evolution of a gas giant around a solar mass star under the influence of successive scatterings with binary and single stars. We show that the chance that a planet $in(1,10)$ au becomes an HJ in a Gyr in a cluster of stellar density $n_*=50$ pc$^{-3}$ and binary fraction $f_mathrm{bin}=0.5$ is about 2% and an additional 4% are forced by the companion star into collision with or tidal disruption by the central host. An empirical fit shows that the total percentage of those outcomes asymptotically reaches an upper limit determined solely by $f_mathrm{bin}$ (e.g., $10%$ at $f_mathrm{bin}=0.3$ and 18% at $f_mathrm{bin}=1$) on a timescale inversely proportional to $n_*$ ($sim$ Gyr for $n_*sim100$ pc$^{-3}$). The ratio of collisions to tidal disruptions is roughly a few, and depends on the tidal model. Therefore, if the giant planet occurrence rate is 10~%, our mechanism implies an HJ occurrence rate of a few times 0.1~% in a Gyr and can thus explain a substantial fraction of the observed rate. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16015v1
Nitrogen as a Tracer of Giant Planet Formation I : A Universal Deep Adiabatic Profile and Semi-analytical Predictions of Disequilibrium Ammonia Abundances in Warm Exoplanetary Atmospheres by Kazumasa Ohno et al. on Wednesday 30 November A major motivation of spectroscopic observations of giant exoplanets is to unveil planet formation processes from atmospheric compositions. Several recent studies suggested that atmospheric nitrogen, like carbon and oxygen, can provide important constrains on planetary formation environments. Since nitrogen chemistry can be far from thermochemical equilibrium in warm atmospheres, we extensively investigate under what conditions, and with what assumptions, the observable NH3 abundances can diagnose an atmosphere's bulk nitrogen abundance. In the first paper of this series, we investigate atmospheric T-P profiles across equilibrium temperature, surface gravity, intrinsic temperature, atmospheric metallicity, and C/O ratio using a 1D radiative-convective equilibrium model. Models with the same intrinsic temperature and surface gravity coincide with a shared "universal" adiabat in the deep atmosphere, across a wide equilibrium temperature range (250--1200 K), which is not seen in hotter or cooler models. We explain this behavior in terms of the classic "radiative zero solution" and then establish a semi-analytical T-P profile of the deep atmospheres of warm exoplanets. This profile is then used to predict vertically quenched NH3 abundances. At solar metallicity, our results show that the quenched NH3 abundance only coincides with the bulk nitrogen abundance (within 10%) at low intrinsic temperature, corresponding to a planet with a sub-Jupiter mass (< 1 MJ) and old age (> 1 Gyr). If a planet has a high metallicity ($ge$ 10$times$ solar) atmosphere, the quenched NH3 abundance significantly underestimates the bulk nitrogen abundance at almost all planetary masses and ages. We suggest modeling and observational strategies to improve the assessment of bulk nitrogen from NH3. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16876v1
A Ghost in Boötes: The Least Luminous Disrupted Dwarf Galaxy by Vedant Chandra et al. on Wednesday 30 November We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars at a distance of 12.5 kpc, and further characterized it with Gaia astrometry and follow-up spectroscopy. Specter is a $25^circ times 1^circ$ stream of stars that is entirely invisible until strict kinematic cuts are applied to remove the Galactic foreground. The spectroscopic members suggest a stellar age $tau gtrsim 12$ Gyr and a mean metallicity $langletext{[Fe/H]}rangle = -1.84_{-0.18}^{+0.16}$, with a significant intrinsic metallicity dispersion $sigma_{ text{[Fe/H]}} = 0.37_{-0.13}^{+0.21}$. We therefore argue that Specter is the disrupted remnant of an ancient dwarf galaxy. With an integrated luminosity $M_{text{V}} approx -2.6$, Specter is by far the least-luminous dwarf galaxy stream known. We estimate that dozens of similar streams are lurking below the detection threshold of current search techniques, and conclude that spectroscopic surveys offer a novel means to identify extremely low surface brightness structures. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.13717v2

Shock-induced stripping of satellite ISM CGM in IllustrisTNG clusters at z sim0 by Hao Li et al. on Wednesday 30 November Using the IllustrisTNG simulation, we study the interaction of large-scale shocks with the circumgalactic medium (CGM) and interstellar medium (ISM) of star-forming (SF) satellite galaxies in galaxy clusters. These shocks are usually produced by mergers and massive accretion. Our visual inspection shows that approximately half of SF satellites have encountered shocks in their host clusters at $zleq0.11$. After a satellite crosses a shock front and enters the postshock region, the ram pressure on it is boosted significantly. Both the CGM and ISM can be severely impacted, either by striping or compression. The stripping of the ISM is particularly important for low-mass galaxies with $log (M_{*}/M_{odot})

Two substellar survivor candidates; one found and one missing by N. Walters et al. on Tuesday 29 November This study presents observations of two possible substellar survivors of post-main sequence engulfment, currently orbiting white dwarf stars. Infrared and optical spectroscopy of GD 1400 reveal a 9.98 h orbital period, where the benchmark brown dwarf has $M_2=68pm8$ M$_{rm Jup}$, $T_{rm eff}approx2100$ K, and a cooling age under 1 Gyr. A substellar mass in the lower range of allowed values is favoured by the gravitational redshift of the primary. Synthetic brown dwarf spectra are able to reproduce the observed CO bands, but lines below the bandhead are notably overpredicted. The known infrared excess towards PG 0010+281 is consistent with a substellar companion, yet no radial velocity or photometric variability is found despite extensive searches. Three independent stellar mass determinations all suggest enhanced mass loss associated with binary evolution, where the youngest total age for an isolated star is $7.5pm2.5$ Gyr. A possible solution to this conundrum is the cannibalization of one or more giant planets, which enhanced mass loss post-main sequence, but were ultimately destroyed. PG 0010+281 is likely orbited by a debris disk that is comfortably exterior to the Roche limit, adding to the growing number of non-canonical disks orbiting white dwarfs. At present, only L-type (brown) dwarfs are known to survive direct engulfment during the post-main sequence, whereas T- and Y-type substellar companions persist at wide separations. These demographics indicate that roughly 50 M$_{rm Jup}$ is required to robustly avoid post-main sequence annihilation, suggesting all closely-orbiting giant planets are consumed, which may contribute to mass loss and magnetic field generation in white dwarfs and their immediate progenitors. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.07022v2
The Gaia-ESO Survey: probing the lithium abundances in old metal-rich dwarf stars in the Solar vicinity by M. L. L. Dantas et al. on Tuesday 29 November We test a scenario in which radial migration could affect the Li abundance pattern of dwarf stars in the solar neighbourhood. This may confirm that the Li abundance in these stars can not serve as a probe for the Li abundance in the interstellar medium. We use the high-quality data (including Li abundances) from the 6th internal Data Release of the Gaia-ESO survey. In this sample, we group stars by similarity in chemical abundances via hierarchical clustering. Our analysis treats both measured Li abundances and upper limits. The Li envelope of the previously identified radially migrated stars is well below the benchmark meteoritic value (0 should not be decreased, as recently proposed in the literature. Our study backs the recent studies that claimed that old dwarfs on the hot side of the dip are efficient probes of the ISM abundance of Li, provided atomic diffusion does not lower significantly the initial Li abundance in the atmospheres of metal-rich objects. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.14132v1
Constraining dark matter decays with cosmic microwave background and weak lensing shear observations by Jozef Bucko et al. on Tuesday 29 November From observations of both low and high redshifts, it is well known that the bulk of dark matter (DM) has to be stable or, at least, very long-lived. However, the possibility that a small fraction of DM is unstable or that all of DM decays with a half-life time ($tau$) significantly larger than the age of the universe is not ruled out. One-body decaying dark matter (DDM) consists of a minimal extension to the $Lambda$CDM model. It causes a modification of the cosmic growth history as well as a suppression of the small-scale clustering signal, providing interesting consequences regarding the $S_8$-tension, the observed differences of the clustering amplitude between weak lensing (WL) and cosmic microwave background (CMB) observations. In this paper we investigate models where a fraction or all DM decays into radiation, focusing on the long-lived regime i.e. $tau gtrsim H_0^{-1}$ ( $H_0^{-1}$ being the Hubble time). We use WL data from the Kilo-Degree Survey (KiDS) and CMB data from Planck. First, we confirm that this DDM model cannot alleviate the $S_8$-tension. We then show that the most constraining power for DM decays does not come from the nonlinear weak lensing data but from CMB via the integrated Sachs-Wolfe effect. From the CMB data alone, we obtain constraints of $tau geq 288$ Gyr if all the DM is assumed to be unstable, and we show that a maximum fraction of $f=0.07$ is allowed to decay assuming the half-life time to be comparable to (or smaller than) one Hubble time. The constraints from the KiDS-1000 WL data are significantly weaker, being at $tau geq 60$ Gyr and $f

We find roughly constant values for the effective radius (r_eff ~ 5 pc) and ellipticity ({epsilon} ~ 0.05), while the S'ersic index (n) and position angle (PA) drop from n ~ 3 to ~ 2 and PA ~ 130{deg} to 90{deg}, respectively. In the mid-infrared, r_eff ~ 12pc, {epsilon} ~ 0.4, and n ~ 1-1.5, with the same PA ~ 90{deg}. The NSC has a stellar mass of log10 (M_nsc / M_Sun) = 7.06 +- 0.31, as derived through B-V, confirmed when using multi-wavelength data, and in agreement with the literature value. Fitting the spectral energy distribution, excluding the mid-infrared data, yields a main stellar population's age of (8 +- 3) Gyr with a metallicity of Z = 0.012 +- 0.006. There is no indication of any significant star formation over the last few Gyr. Whether gas and dust were dynamically kept out or evacuated from the central cavity remains unclear. The best-fit suggests an excess of flux in the mid-infrared bands, with further indications that the center of the mid-infrared structure is displaced with respect to the optical center of the NSC. We discuss five potential scenarios, none of them fully explaining both the observed photometry and structure. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.13997v1
Two substellar survivor candidates; one found and one missing by N. Walters et al. on Monday 28 November This study presents observations of two possible substellar survivors of post-main sequence engulfment, currently orbiting white dwarf stars. Infrared and optical spectroscopy of GD 1400 reveal a 9.98 h orbital period, where the benchmark brown dwarf has $M_2=68pm8$ M$_{rm Jup}$, $T_{rm eff}approx2100$ K, and a cooling age under 1 Gyr. A substellar mass in the lower range of allowed values is favoured by the gravitational redshift of the primary. Synthetic brown dwarf spectra are able to reproduce the observed CO bands, but lines below the bandhead are notably overpredicted. The known infrared excess towards PG 0010+281 is consistent with a substellar companion, yet no radial velocity or photometric variability is found despite extensive searches. Three independent stellar mass determinations all suggest enhanced mass loss associated with binary evolution, where the youngest total age for an isolated star is $7.5pm2.5$ Gyr. A possible solution to this conundrum is the cannibalization of one or more giant planets, which enhanced mass loss post-main sequence, but were ultimately destroyed. PG 0010+281 is likely orbited by a debris disk that is comfortably exterior to the Roche limit, adding to the growing number of non-canonical disks orbiting white dwarfs. At present, only L-type (brown) dwarfs are known to survive direct engulfment during the post-main sequence, whereas T- and Y-type substellar companions persist at wide separations. These demographics indicate that roughly 50 M$_{rm Jup}$ is required to robustly avoid post-main sequence annihilation, suggesting all closely-orbiting giant planets are consumed, which may contribute to mass loss and magnetic field generation in white dwarfs and their immediate progenitors. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.07022v2

Galaxy and Mass Assembly GAMA : Extended Intra-Group Light in a group at z=0 2 from deep Hyper-Suprime Cam images by Cristina Martinez-Lombilla et al. on Thursday 24 November We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxies. We examine the intra-group light (IGL) of the group 400138 ($M_{rm{dyn}}= 1.3 pm 0.5 times 10^{13} $M$_{odot}$, $zsim 0.2$) from the Galaxy And Mass Assembly (GAMA) survey using Hyper-Suprime Cam Subaru Strategic Program Public Data Release 2 (HSC-PDR2) images in $g$, $r$, and $i$ bands. We present the most extended IGL measurement to date, reaching down to $mu_{g}^{rm{lim}}=30.76$ mag arcsec$^{-2}$ ($3 sigma$; $10 times 10$ arcsec$^{2}$) at a semi-major axis of 275 kpc. The IGL shows mean colour values of $g-i=0.92$, $g-r=0.60$, and $r-i=0.32$ ($pm$0.01). The IGL stellar populations are younger ($2-2.5$ Gyr) and less metal-rich ([Fe/H] $ sim -$0.4) than those of the host group galaxies. We find a range of IGL fractions as a function of total group luminosity of $sim 2-36 %$ depending on the definition of IGL, with larger fractions the bluer the observation wavelength. The early-type to late-type galaxy ratio suggests that 400138 is a more evolved group, dominated by ETGs, and the IGL fraction agrees with that of other similarly evolved groups. These results are consistent with tidal stripping of the outer parts of Milky Way-like galaxies as the main driver of the IGL build-up. This is supported by the detection of substructure in the IGL towards the galaxy member 1660615 suggesting a recent interaction ($
Short GRB Host Galaxies II A Legacy Sample of Redshifts, Stellar Population Properties, and Implications for their Neutron Star Merger Origins by Anya E. Nugent et al. on Thursday 24 November We present the stellar population properties of 69 short gamma-ray burst (GRB) host galaxies, representing the largest uniformly-modeled sample to-date. Using the Prospector stellar population inference code, we jointly fit photometry and/or spectroscopy of each host galaxy. We find a population median redshift of $z=0.64^{+0.83}_{-0.32}$ ($68%$ confidence), including 10 new or revised photometric redshifts at $zgtrsim1$. We further find a median mass-weighted age of $t_m=0.8^{+2.71}_{-0.53}$Gyr, stellar mass of $log(M_*/M_odot)=9.69^{+0.75}_{-0.65}$, star formation rate of SFR=$1.44^{+9.37}_{-1.35}M_odot$yr$^{-1}$, stellar metallicity of $log(Z_*/Z_odot)=-0.38^{+0.44}_{-0.42}$, and dust attenuation of $A_V=0.43^{+0.85}_{-0.36}$~mag (68% confidence). Overall, the majority of short GRB hosts are star-forming ($approx84%$), with small fractions that are either transitioning ($approx6%$) or quiescent ($approx10%$); however, we observe a much larger fraction ($approx40%$) of quiescent and transitioning hosts at $zlesssim0.25$, commensurate with galaxy evolution. We find that short GRB hosts populate the star-forming main sequence of normal field galaxies, but do not include as many high-mass galaxies, implying that their binary neutron star (BNS) merger progenitors are dependent on a combination of host star formation and stellar mass. The distribution of ages and redshifts implies a broad delay-time distribution, with a fast-merging channel at $z>1$ and a decreased BNS formation efficiency at lower redshifts. If short GRB hosts are representative of BNS merger hosts within the horizon of current gravitational wave detectors, these results can inform future searches for electromagnetic counterparts. All of the data and modeling products are available on the BRIGHT website. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2206.01764v3
