The Astrophysics PodcastDr. Abigail Polin -- Astrophysics Q & AIn this week's episode, Dr. Abigail Polin joins us to answer your questions from the internet, on a variety of topics tangentially related to astrophysics! Questions range from the basic and fundamental to the obscure and weird. Answers are totally unprepared and rambling. Our guests this week are Dr. Abigail Polin, PLUS an extra-special mystery guest!2025-07-011h 25The Astrophysics PodcastDr. Andrea Derdzinski -- How do we see black holes?A black hole is so dense, its gravitational field prevents anything from escaping, including light. You would think that would make them the "blackest" things in the universe; how in the world do we know they are there? Dr. Andrea Derdzinski tells us about how we detect black holes, either due to the gravitational waves they produce, or due to their interaction with material orbiting around them, which paradoxically can make them some of the brightest objects in the universe.2025-06-0155 minThe Astrophysics PodcastDr. Jared Goldberg -- Does Betelgeuse have a Betelbuddy?Up in Orion's shoulder sits Betelgeuse, a supergiant star near the end of its life. The surface of Betelgeuse has been roiling and pulsing for centuries, as long as humans have recorded its modulated luminosity. Dr. Jared Goldberg is a postdoctoral research fellow at the Center for Computational Astrophysics in the Flatiron Institute in New York City. Dr. Golberg has been developing computer models for Betelgeuse to help understand and interpret its oscillations over time.2025-05-011h 04The Astrophysics PodcastDr. Yvette Cendes -- Black Holes on the RadioWhat happens when a black hole eats up a star? Apparently a lot of things happen, and if you wait around awhile and look in the radio, even more things happen! Dr. Yvette Cendes tells us what it's like to be a radio astronomer and about her latest research into tidal disruption events (TDE's), when a black hole shreds up a star and eats it, producing a dramatic light show across the electromagnetic spectrum.2025-04-0153 minThe Astrophysics PodcastDr. Maxim Lyutikov -- How do you make a Fast Radio Burst?Some things happen out in the universe that are too powerful to make in a lab. Other phenomena are so coherent and well-ordered, we can't figure out how they can be made without a lab! Fast radio bursts are an incomprehensible combination of both; they are extremely powerful, highly coherent, and very rapid bursts of radio emission. Dr. Maxim Lyutikov spends a lot of his time pondering how these bursts could possibly be made, and all the data seems to point to the most extreme physics imaginable: neutron stars at the highest densities we can imagine, with extremely strong...2025-03-011h 07The Astrophysics PodcastDr. Lindsey Kwok -- The Forensic Science of SupernovaeHow do we know so much about supernovae, when all we see is this little point of light getting brighter and then dimmer over time? Given this minimal data, we can often say what type of star exploded, and even some details about how the explosion took place. Supernova astronomers are a lot like forensic scientists dusting for fingerprints and getting DNA samples at the scene of a crime. But instead of a typical crime scene, they are investigating the death of an entire solar system. Dr. Lindsey Kwok is a CIERA fellow at Northwestern University and an expert...2025-02-0155 minThe Astrophysics PodcastDr. Paul Duffell -- The Universe on a Computer (with host Dr. Abigail Polin)How big a computer do you need to simulate a supernova? Or a planet being formed? Or a black hole swallowing gas? Many astrophysicists spend their time developing computational models to simulate these systems and learn how they evolve. We discuss these computer simulations with Purdue Professor Dr. Paul Duffell. In this first episode of season 2, Dr. Abigail Polin takes over as host.2025-01-011h 10The Astrophysics PodcastDr. Brenna Mockler -- When Black Holes Get HungryWhat do black holes like to eat? Sometimes a steady diet of interstellar gas just isn't enough and a black hole needs to snack on a whole star. No judgment, we all get that way sometimes. But it can lead to some extremely energetic outflows, visible from across the universe. Dr. Brenna Mockler tells us all about these events, called "Tidal Disruption Events", and what we can learn from observing them.2024-12-011h 00The Astrophysics PodcastDr. Dan Milisavljevic -- Into the Time DomainOur universe isn't just a static, unchanging backdrop. It is constantly changing in time and we now have the technology to image it over and over again to explore all those changes. This is called Time Domain Astronomy, and Danny Milisavljevic is an expert in this field. He spends a lot of his time on the forensic science of exploding stars, to gain clues about the underlying processes that caused the explosion in the first place.2024-11-0155 minThe Astrophysics PodcastDr. Katelyn Breivik -- How Binary Stars EvolveWhat would our solar system be like if we had two suns? Actually, this situation could be more common than you might think, as most stars are in binary systems. If a star is in a binary pair, how does that affect its life and death? Dr. Katelyn Breivik of Carnegie Mellon University tells us all about these systems and what scientists and other curious minds can learn from them.2024-10-011h 09The Astrophysics PodcastDr. Kyoungsoo Lee -- Our Galactic NeighborhoodWhat's the biggest thing in the universe, besides the universe itself? Well, stars live in galaxies, and galaxies live in large collections called galaxy clusters. Astronomers can study these titanic clusters of galaxies to learn about how they grow and merge with each other to assemble the universe we live in today. Dr. Kyoung-Soo Lee takes us on a journey to the largest scales in the cosmos.2024-09-011h 10
General Witchfinders: The British Horror Podcast48 - The House that Dripped blood"The House That Dripped Blood" is a 1971 British anthology horror film directed by Peter Duffell and distributed by Amicus Productions. The film is a collection of four short stories, each concerning a series of inhabitants of the eponymous building. Denholm Elliott appears in the segment "Method for Murder," playing Charles Hillyer. He is joined by Joanna Dunham, who portrays Alice Hillyer, Charles' wife. Peter Cushing stars in the segment "Waxworks," portraying Philip Grayson. Joss Ackland (known for "Lethal Weapon 2," "Watership Down," and "Bill and Ted's Bogus Journey," among over 100 other films) plays...2024-08-191h 20The Astrophysics PodcastDr. Jason Wang -- Taking a Photo of an ExoplanetFor centuries, all that we have known about planets was confined to our own solar system, and its occasionally-changing number of planets (eight as of now). But in the past several decades, astronomers have developed increasingly sophisticated techniques for detecting planets outside our solar system, orbiting distant stars many light-years away. Dr. Jason Wang is an innovator who has developed powerful data analysis methods which have allowed us to take direct images of these exoplanets.2024-08-0146 minThe Astrophysics PodcastDr. Rosalba Perna -- The Neighborhood of a Supermassive Black HolePlanets orbit stars, and moons orbit planets, so what orbits a supermassive black hole? Possibly a whole lot of stuff, including a gaseous disk, thousands of stars and more "normal size" black holes! Dr. Rosalba Perna tells us about all the crazy things that could be orbiting around the supermassive black holes that we detect at the center of active galaxies.2024-07-011h 04
An Evolving Man PodcastComplex PTSD - What Is The Outer Critic? How Does It Differ From The Inner Critic? | Piers CrossWhat is the outer critic especially in terms of childhood trauma, complex PTSD and boarding school syndrome?How does the outer critic come to the fore? And what is the outer critic's link to the inner aspect?Today I wanted to offer some reflections about how this part of our psyche plays out.I quote from Pete Walker and his book, Complex PTSD and also from Nick Duffell's Wounded Leaders and his take on dissociation.If you have learned to dissociate from the unwanted parts of yourself you will have a...2024-06-2610 minThe Astrophysics PodcastDr. Soham Mandal -- What Happens to Supernovae After they Explode?When a star explodes, it's not finished having an impact on its surroundings. For the next thousand years or so, we can still see it as a supernova remnant, when the explosion has expanded to large enough scales that we can actually resolve an image of the explosion with modern telescopes like JWST, and it's even possible to do a forensic analysis to learn more about the cause of death. We will be talking about supernova remnants with Dr. Soham Mandal, who just recently earned his PhD from Purdue University.2024-06-0150 minThe Astrophysics PodcastDr. Yuan Li -- Our Turbulent UniverseWhat is turbulence? You've probably experienced it before on a plane (or perhaps on a river) but you might not know precisely what it is. But turbulence is all around us, and in particular we find it on some of the largest scales in the universe. Professor Yuan Li talks about turbulence and also a little unrelated bit about Mira, an unusual star with a tail!2024-05-0156 minThe Astrophysics PodcastDr. Ashley Villar -- Big Data in AstrophysicsAstronomers deal with huge datasets, and they are about to get even bigger with the construction of the Vera Rubin Observatory. When you can detect a million supernovae per year, how do we make sense of this data and decide which ones are the "most interesting" to study? Professor Ashley Villar at the Center for Astrophysics | Harvard & Smithsonian has made her career out of developing machine learning techniques to answer this very question.2024-04-011h 03The Astrophysics PodcastDr. Frank Timmes -- Pulsing White Dwarfs, Neutrinos, and the Infrastructure of ResearchWhat are neutrinos and where do they come from? How do we know what's going on in the interior of a star when we can only see the surface? How does a paper get accepted into a scientific journal? We discuss these questions and more with Frank Timmes, professor at Arizona State University and Associate Editor-in-Chief of a number of scientific journals run by the American Astronomical Society.2024-03-0157 minThe Astrophysics PodcastDr. Erica Nelson -- Watching the First Galaxies FormHow did the galaxies form and how can we learn about them? Professor Erica Nelson of the University of Colorado, Boulder tells us how we use the James Webb Space Telescope (JWST) to look back in time and learn about the initial formation of structure in the universe.2024-02-0159 min
