Collapsing Halo Cores with Self-Interacting Dark Matter - Kimberly K. Boddy, University Austin-Texas

Large self interactions between dark matter particles alter the predicted properties of dark matter halos and may help address small-scale structure anomalies, while maintaining the successes of standard cold dark matter at large cosmological scales. Self interactions allow for efficient heat transfer within a halo, but they also alter the dynamics of satellite subhalos. In this talk, I will discuss how the choice of the particle physics model for self interactions, as well as the astrophysical environment, impacts the phases of halo/subhalo evolution.
