How to Destroy a Galaxy with Dark Matter

Explore a fascinating physics seminar where Princeton University's Mariangela Lisanti delves into the intriguing relationship between Cold Dark Matter (CDM) and galactic destruction. Learn about groundbreaking cosmological hydrodynamical simulations that investigate how a small portion of dissipative dark matter can dramatically impact galaxy formation and evolution. Discover how the Cold Dark Matter hypothesis, while proven successful on universal scales, faces new challenges at the sub-galactic level. Examine the effects of minimal Atomic Dark Matter on Milky Way-like galaxies, their dwarf galaxies, and dark substructure. Understand how even a minor fraction of dark matter with unique dynamics can potentially lead to galactic destruction, demonstrating galaxies' remarkable sensitivity to dark-sector physics.
