Diversity in density profiles of self-interacting dark matter satellite halos
Felix Kahlhoefer, Manoj Kaplinghat, Tracy R. Slatyer +1
We present results from N-body simulations of self-interacting dark matter (SIDM) subhalos, which could host ultra-faint dwarf spheroidal galaxies, inside a Milky-Way-like main hal…

Enhanced n-body annihilation of dark matter and its indirect signatures
Mohammad Hossein Namjoo, Tracy R. Slatyer, Chih-Liang Wu
We examine the possible indirect signatures of dark matter annihilation processes with a non-standard scaling with the dark matter density, and in particular the case where more th…

Early-Universe Constraints on Dark Matter-Baryon Scattering and their Implications for a Global 21cm Signal
Tracy R. Slatyer, Chih-Liang Wu
We present and compare several cosmological constraints on the cross section for elastic scattering between dark matter (DM) and baryons, for cross sections with a range of power-l…
