John Batchelor Hotel Mars, Wednesday, July 30, 2025


Listen Later

John and I introduced Megan to our Hotel Mars program for a discussion of her work with dormant blackholes and more. Megan presented research on tidal disruption events (TDEs) observed using the James Webb Space Telescope, which has revealed previously dormant black holes becoming active and providing insights into their environmental effects. The discussion covered the physics of TDEs, including their impact on surrounding gas and dust, as well as the challenges of studying dormant black holes and their relationship with galaxy size. The conversation concluded with a discussion about the limitations of current telescopes, the importance of time-domain astronomy, and the potential impact of the Golden Dome project on the space industry.
