SUMMARY:Collapsing Halo Cores with Self-Interacting Dark Matter\, Theo
 ry Seminar (High Energy/Cosmology)\, Kimberly K. Boddy\, University Te
 xas\, Austin
DESCRIPTION:Large self interactions between dark matter particles alte
 r the predicted properties of dark matter halos and may help address s
 mall-scale structure anomalies\, while maintaining the successes of st
 andard cold dark matter at large cosmological scales. Self interaction
 s allow for efficient heat transfer within a halo\, but they also alte
 r the dynamics of satellite subhalos. In this talk\, I will discuss ho
 w the choice of the particle physics model for self interactions\, as 
 well as the astrophysical environment\, impacts the phases of halo/sub
 halo evolution. Video recording: https://youtu.be/S2r__SLer5I
