    Dr. Paul Duffell -- The Universe on a Computer (with host Dr. Abigail Polin)
    Jan 1 2025

    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.

  • Dr. Brenna Mockler -- When Black Holes Get Hungry

    Dr. Brenna Mockler -- When Black Holes Get Hungry
    Dec 1 2024

    What 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.

  • Dr. Dan Milisavljevic -- Into the Time Domain

    Dr. Dan Milisavljevic -- Into the Time Domain
    Nov 1 2024

    Our 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.
