SUMMARY:Workshop / Seminar:Cosmo-Astro Seminar | The progenitor’s impact on globular cluster stellar stream models
DESCRIPTION:Dynamically cold stellar streams from globular cluster progenitors are important probes of the Milky Way’s dark matter\; their kinematic heating\, for example\, could help constrain the physical properties of dark matter subhalos. Direct N-body simulations are considered the ground truth\, but are often an impractical choice due to the computational expense. Particle-spray methods successfully produce stream models very quickly\, but are reliant on making certain approximations about escape physics. We have bridged the gap between these approaches with KRIOS\, a new basis-expansion N-body code. In this talk\, I will provide a high-level review of KRIOS’ technical details\, discuss preliminary results on streams from spinning progenitors\, and address the potential complementarity between KRIOS and the particle-spray distribution function developed here in Ann Arbor.
