Semi-Analytic Modeling of Dark Matter Subhalo Encounters with Thin Stellar Streams: Statistical Predictions for GD-1-like Streams in CDM
Duncan K. Adams, Aditya Parikh, Oren Slone +3
Stellar streams from disrupted globular clusters are dynamically cold structures that are sensitive to perturbations from dark matter subhalos, allowing them in principle to trace…
Using Strong Lensing to Detect Subhalos with Steep Inner Density Profiles
Kassidy E. Kollmann, James W. Nightingale, Mariangela Lisanti +2
The inner region of a subhalo's density distribution is particularly sensitive to dark matter microphysics, with alternative dark matter models leading to both cored and steeply-ri…
Probabilistic Inference of the Structure and Orbit of Milky Way Satellites with Semi-Analytic Modeling
Dylan Folsom, Oren Slone, Mariangela Lisanti +2
Semi-analytic modeling furnishes an efficient avenue for characterizing the properties of dark matter halos associated with satellites of Milky Way-like systems, as it easily accou…
Numerical Challenges in Modeling Gravothermal Collapse in Self-Interacting Dark Matter Halos
Igor Palubski, Oren Slone, Manoj Kaplinghat +2
When dark matter has a large cross section for self scattering, halos can undergo a process known as gravothermal core collapse, where the inner core rapidly increases in density a…
Numerical evolution of self-gravitating halos of self-interacting dark matter
Marc Kamionkowski, Kris Sigurdson, Oren Slone
We discuss a modification of a recently developed numerical scheme for evolving spherically symmetric self-gravitating systems to include the effects of self-interacting dark matte…
Effects of Dark Matter Self Interactions on Sagittarius and Its Stream
Connor Hainje, Oren Slone, Mariangela Lisanti +1
This work explores how assumptions regarding the particle-physics nature of dark matter can alter the evolution of the Sagittarius (Sgr) dwarf spheroidal galaxy and its expansive s…
