How do supermassive black holes actually form in the early universe? Is the Cosmological Constant not so constant after all? And what would be on the astrophysical menu at a Cosmic Brunch? To find out, Dr. Charles Liu and co-host Allen Liu welcome astrophysicist Thresa Kelly, who is a second year grad student working on her PhD at the Rochester Institute of Technology. As always, though, we start off with the day's joyfully cool cosmic thing, one of the recent studies made using the Dark Energy Spectroscopic Instrument, aka DESI, located at Kitt Peak National Observatory near Tucson, Arizona. According to the DESI team's research, there is a about a 95% chance that the dark energy levels in the universe have changed over cosmic time. This “Dynamical Dark Energy model” offers the first, tiny hint that the Cosmological Constant may not be so constant after all. Thresa, who is using DESI and other sources for her work putting together a catalog of AGNs, or active galactic nuclei – the supermassive black holes found at the center of galaxies, tells us about what DESI is trying to do and why it's so important. The end goal of Thresa's project is to estimate the black hole masses of AGNs, and she's gotten spectra data on over 2,000 objects that have been observed using DESI. Thresa can't get into the details of her catalog, which hasn't been published yet and includes about 14,000 objects, but Allen and Chuck join her in a discussion of what's going on with black hole masses, accretion discs, Eddington Luminosity, black hole growth, galactic evolution, and more. Our first audience question comes from Kathryn, who asks, “When we look through a standard telescope looking at "past" versions of planets/stars/etc., how far back in the past are we observing?” Thresa explains how we use red shift to measure how long light from a galaxy takes to reach us to help us determine how far in the past the objects are. For instance, an AGN with a red shift of 7 can reach back to the period of “Cosmic Dawn” or, as Thresa puts it, “Cosmic Brunch” taking place 12 billion years ago. Thresa talks about her experience in an REU, or “Research Experiences for Undergraduates,” funded by the NSF, which enabled her to spend time studying at the University of Hawaii and cemented her desire to go to grad school, get a PhD, and become a “real scientist.” She explains how each step of her career brought her from Kansas to where she is today. Our next audience question comes from Walter: “If a quasar's jets are aimed directly away from Earth, would we then not be able to see the supermassive black hole?” Thresa says that depends on how you define “seeing” a black hole, and that even without visible light, you can discern black holes by looking at other wavelengths like x-rays and ultraviolet rays which are generated by different component areas of the black hole like the corona, accretion disk, or the torus. Chuck notices a shelf of games behind Thresa and asks her about them. She pulls out Stardew Valley, a farming simulator she plays with her fiancé and her fellow grad students. It's not long until Chuck, Allen and Thresa are geeking out about Dungeons and Dragons. Finally, Chuck asks Thresa to speculate on a specific scientific discovery that may come out of her PhD thesis work. Her answer: figuring out how supermassive black holes actually form in the early universe. If you'd like to know more about Thresa Kelly, you can find her on LinkedIn.

In this episode, Eddie Pinero dives into the powerful shift from hoping for miracles to creating your own wins. Using a vivid metaphor of an underdog football team, he breaks down how to take control of your life by believing in your own potential, defining your North Star, and structuring your days for success. Join Eddie as he explores how to stop waiting for that one-in-a-thousand chance and start building a life where winning is the norm.More from Eddie Pinero:Wear the Lifestyle: www.AGNS.lifestyleMonday Motivation Newsletter: https://www.eddiepinero.com/newsletterBusiness Inquiries - http://www.yourworldwithin.com/contact#liveinspired #yourworldwithin #motivation

A message from the version of you who never stopped believing.This speech explores what life can become when belief is sustained through uncertainty, quiet seasons, and slow progress. It's a reminder that consistency compounds, trust is built over time, and staying loyal to yourself changes everything.More from Eddie Pinero:Support the brand/wear the message: www.AGNS.lifestyleMonday Motivation Newsletter: Business Inquiries - http://www.yourworldwithin.com/contact#liveinspired #yourworldwithin #motivation

In this episode, Eddie revisits the parable of the two wolves and reframes it for real life. It's not about “good vs. evil,” it's about attention, meaning, and what you choose to nurture. Through personal stories from Covid, failed ventures, and the creation of AGNS, Eddie shows how the wolf you feed becomes the path you walk.More from Eddie Pinero:Monday Motivation Newsletter: https://www.eddiepinero.com/newsletterYour World Within Podcast: https://yourworldwithin.libsyn.com/Stream these tracks on Spotify - https://spoti.fi/2BLf6pBInstagram - @your_world_within and @IamEddiePineroTikTok - your_world_withinFacebook - https://www.facebook.com/YourworldwithinTwitter - https://www.twitter.com/IamEddiePineroBusiness Inquiries - http://www.yourworldwithin.com/contact#liveinspired #yourworldwithin #motivation

This episode is about the moment you finally stop refusing the call. From Luke Skywalker to Frodo Baggins to the small, quiet fears we face every day...life presents the opening, but only you decide if it becomes a turning point. I share a personal story about saying “yes” when it scared me, and why the smallest acts of courage often change everything. This is about getting out of your own way, answering what's been calling you, and choosing to step forward, shaky hands and all.More from Eddie Pinero:Wear the brand: www.AGNS.lifestyleMonday Motivation Newsletter: https://www.eddiepinero.com/newsletterBusiness Inquiries - http://www.yourworldwithin.com/contact#liveinspired #yourworldwithin #motivation

BREAK YOUR NEGATIVE THINKING (Best Motivational Speech For Positive Thinking) begins with a powerful reminder that perspective is everything. In this opening segment, Eddie reflects on the illusion of false summits, those moments when you think you've made it, only to realize there's more to climb. What seems like failure or stagnation is often just life testing your endurance and focus. By shifting how we interpret those moments, we break free from negative thinking and uncover the strength hidden in the struggle. This episode reminds us that progress isn't about the peak, it's about learning to see the beauty, growth, and meaning in the climb itself.More from Eddie Pinero:Wear the mindset: www.AGNS.lifestyleMonday Motivation Newsletter: https://www.eddiepinero.com/newsletterYour World Within Podcast: https://yourworldwithin.libsyn.com/Stream these tracks on Spotify - https://spoti.fi/2BLf6pBInstagram - @your_world_within and @IamEddiePineroTikTok - your_world_withinFacebook - https://www.facebook.com/YourworldwithinTwitter - https://www.twitter.com/IamEddiePineroBusiness Inquiries - http://www.yourworldwithin.com/contact#liveinspired #yourworldwithin #motivation

Welcome to the first ever episode of the LIUniverse, your happy half hour dose of cosmic conversation and geeky banter with host Dr. Charles Liu! In this episode, we talk quasars, “The Expanse”, and more with our guest Jimmy Negus, PhD candidate at the University of Colorado Boulder, and with our co-host Allen Liu. The trio discuss Jimmy's research on active galactic nuclei (AGNs), including some that might not even be in a galaxy's nucleus at all, plus some sci-fi stories that have them hooked, and some in which the science really misses the mark. You'll discover how something “only” the size of the orbit of Mercury could outshine an entire galaxy, learn how the highest note on the piano can help examine the atmosphere, and find out how a telescope survey with a tortured acronym is bringing a new dimension to astronomical research. You can also explore how Jimmy helps students understand the truly impressive size of our neighborhood in space – even in his new 10-billion-to-1 scale model. We also answer questions from students and from our patrons, and we have some great ones to kick us off. Ben asks, what's the difference between a black hole, an AGN and a quasar? Sadie asks, why choose astronomy over other fields of science? Plus, our patron Walter wonders, is there anything in the universe that doesn't spin or vibrate? We're so glad to finally be able to share the LIUniverse podcast with all of you, and we hope you continue to geek out with us for many episodes to come!
