Gravothermal collapse of self-interacting dark-matter halos with anisotropic velocity distributions
Marc Kamionkowski, Kris Sigurdson
Self-gravitating galactic halos composed of self-interacting dark matter exhibit the formation of a highly dense core at the galactic center--a gravothermal collapse. Analytic mode…

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…

Evolution of self-gravitating spherical dark-matter halos with and without new physics
Marc Kamionkowski, Kris R. Sigurdson
We present an efficient numerical algorithm for evolving self-gravitating systems of dark-matter particles that leverages the assumption of spherical symmetry to reduce the nominal…
