Dark Matter Cores and Cusps in Spiral Galaxies and their Explanations
Manoj Kaplinghat, Tao Ren, Hai-Bo Yu
We compare proposed solutions to the core vs cusp issue of spiral galaxies, which has also been framed as a diversity problem, and demonstrate that the cuspiness of dark matter hal…
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…
Too Big To Fail in Light of Gaia
Manoj Kaplinghat, Mauro Valli, Hai-Bo Yu
We point out an anti-correlation between the central dark matter (DM) densities of the bright Milky Way dwarf spheroidal galaxies (dSphs) and their orbital pericenter distances inf…
The Milky Way's Halo and Subhalos in Self-Interacting Dark Matter
Victor H. Robles, Tyler Kelley, James S. Bullock +1
We perform high-resolution simulations of a MW-like galaxy in a self-interacting cold dark matter model with elastic cross section over mass of (SIDM) and compare to…
Detecting Dark Matter Cores in Galaxy Clusters with Strong Lensing
Kevin E. Andrade, Quinn Minor, Anna Nierenberg +1
We test the ability of strong lensing data to constrain the size of a central core in the dark matter halos of galaxy clusters, using Abell 611 as a prototype. Using simulated data…
Accelerated core collapse in tidally stripped self-interacting dark matter halos
Hiroya Nishikawa, Kimberly K. Boddy, Manoj Kaplinghat
We use a semianalytic approach that is calibrated to N-body simulations to study the evolution of self-interacting dark matter cores in galaxies. We demarcate the regime where the…
