V Hirošimi na Japonskem so zbrani voditelji sedmih gospodarsko najbolj razvitih držav sveta. Lotili so se že nekaterih pomembnih tem. Ameriške oblasti naj bi predstavile nabor dodatnih sankcij proti Rusiji; pri tem ne želijo le podpore skupine G7, ampak tudi članic skupine G21. Številne med njimi imajo tesne vezi tako z Moskvo kot Pekingom. Vrha se bo po neuradnih podatkih udeležil tudi ukrajinski predsednik Volodimir Zelenski in nagovoril zbrane. Nekateri drugi poudarki oddaje: - Na vzhodu države se še sprožajo plazovi. Pristojni ob sanaciji ocenjujejo škodo. Ta naj bi samo v Slovenskih goricah presegla tri milijone evrov. Lokalne skupnosti zato pozivajo državo k takojšnji pomoči. - Kako se bo dejansko izvajala dolgotrajna oskrba? Centri za socialno delo, ki naj bi postali vstopne točke, svarijo, da imajo premalo ljudi. - Za naslov prvaka nogometne lige Evropa se bosta pomerili Sevilla in Roma; finalista konferenčne lige pa sta West Ham United in Fiorentina.

Nuestro "Poca broma" de este martes ha prestado especial atención a África. Handi Mansur, representante del Frente Polisario en Canarias, nos ha hablado del conflicto reabierto recientemente entre el Sáhara y Marruecos. Por otro lado, Canarias recibe, un día sí y otro también, numerosas personas migrantes que llegan a bordo de cayucos y pateras, algo sobre lo que ha girado la conversación mantenida con Juan Carlos Lorenzo, portavoz de CEAR (Confederación Española de Ayuda al Refugiado), en Canarias. Además, como es habitual, a pesar de que tratamos temas muy serios que nos afectan de un modo u otro, no perdemos la perspectiva de la ironía y la broma, una parte importante del programa que nos trae el humor de Riki Rizo.

Fakultät für Physik - Digitale Hochschulschriften der LMU - Teil 01/05

In den letzten Jahren wurden 373 ausgedehnte Roentgenquellen in der ROSAT Himmelsdurchmusterung (RASS) als Supernova Ueberreste (SNRs) Kandidaten identifiziert (Busser, 1998). Ein Ziel der vorliegenden Arbeit war die genaue Untersuchung und Identifizierung dieser Galaktischen SNR Kandidaten an Hand ihrer Roentgen- und Radiomorphologie. Diese Analyse erlaubte es fuer die untersuchten Objekte, zwischen extragalaktischen Hintergrundsquellen und SNR Kandidaten zu unterscheiden. Rund 16% der 373 Kandidaten (59) stellten sich als wahrscheinliche Galaxien oder Galaxienhaufen heraus, wohingegen sich 99 Kandidaten als unechte Hintergrundsquellen erwiesen. Nachbeobachtungen der besten Kandidaten wurden im Radioband sowie im Roentgenband durchgefuehrt und G38.7-1.4 und G296.7-0.9 als SNRs identifiziert. Neun Objekte wurden als hervorragende Kandidaten und weitere 90 als moegliche SNRs auf Grund ihrer Radio- und Roentgenmorphologie klassifiert. Die restlichen 114 Quellen zeigen kaum Indizien fuer SNRs and wurden deswegen als SNR Kandidaten verworfen. Ein Vergleich dieser Ergebnisse mit denen einer Simulation von Busser zeigt, dass weniger SNR Kandidaten im RASS gefunden wurden als von der Simulation erwartet. Um eine Uebereinstimmung beider Ergebnisse zu erreichen, muss eine hoehere interstellare Dichte, eine geringe Explosionsenergie und eine geringe galaktische SN Rate angenommen werden. Der zweite Teil dieser Arbeit beschreibt die detailierte Untersuchung dreier galaktischer SNRs. XMM-Newton Beobachtung von RCW 103: RCW 103 ist ein schalenfoermiger SNR mit einer kompakten Roentgenquelle im Zentrum. Es ist allerdings noch unklar, ob RCW 103 von einer Supernova (SN) Ia oder einem Kernkollaps SN stammt. Allerdings konnte gezeigt werden, dass RCW 103 in verschiedenen Linienemissionen die gleiche Ausdehnung hat, sowie eine geringe Expansionsgeschwindigkeit leichter Elemente wie z. Bsp. Magnesium aufweist, was fuer Kernkollaps SN erwartet wird. Schliesslich liefert die Existenz einer zentralen Punktquelle, die wahrscheinlich einem Neutronenstern und seinem Begleitstern zuzuordnen ist, ein ueberzeugendes Argument fuer ein Kernkollaps Szenario. XMM-Newton Beobachtung von G21.5-0.9: G21.5-0.9 ist ein dem Krebsnebel aehnlichen SNR mit einer kompakten Roentgenquelle im Zentrum. XMM-Newton Daten zeigen, dass der diffuse Nebel von G21.5-0.9 am besten durch ein Potenzgesetz beschrieben wird, dessen Spektralindex von 1.72 im Zentrum bis 2.43 am Rande des Halos ansteigt. Weder Linienemission noch Randaufhellung konnte im Halo gefunden werden und auch die spaehrische Symnmetrie legen eine Interpretation des aeusseren Halos als eine Ausdehnung des zentralen Synchrotronnebels nahe. ROSAT Beobachtung von G65.3+5.7: Das Roentgenspektrum von G65.3+5.7 zeigt thermische Roentgenemission, welches durch ein Raymond-Smith Model mit einer Durchschnittstemperatur von 0.20 keV und einer geringen Umgebungsdichte von ~0.019~cm^{-3} beschrieben wird. Unter der Annahme einer Entfernung von 1 kpc und unter der Benutzung der Sedov Gleichungen, erhaehlt man ein Alter von ~ 27500 Jahren, eine Explosionsenergie von ~ 0.18 x 10^{51} erg und eine Leuchtkraft L_x ~ 9.9 x 10^{34} erg. Der Radiopulsar PSR J1931+30 befindet sich in G65.3+5.7. Da keine zeitliche Frequenzaenderung bekannt ist, wurde mit Hilfe einer oberen Schranke der Roentgenzaehlrate und unter Annahme eines Spektrums, das dem des Krebsnebels aehnelt, ein Roentgenfluss f_x = 3.93 x 10^{-13} erg~cm^{-2} s^{-1} bestimmt, das einer Leuchtkraft L_x = 4.32 x 10^{32} erg entspricht und folglich einer unteren Schranke des charakteristischen Alters von 1400 Jahren entspricht.
