A model for core formation in dark matter haloes and ultra diffuse galaxies by outflow episodes
Jonathan Freundlich, Avishai Dekel, Fangzhou Jiang +5
We present a simple model for the response of a dissipationless spherical system to an instantaneous mass change at its center, describing the formation of flat cores in dark matte…
Dark-Matter Halo Profiles of a General Cusp/Core with Analytic Velocity and Potential
Avishai Dekel, Guy Ishai, Aaron A. Dutton +1
We present useful functions for the profiles of dark-matter (DM) haloes with a free inner slope, from cusps to cores, where the profiles of density, mass-velocity and potential are…
A Dark-Matter Halo Profile allowing a Variable Cusp-Core with Analytic Velocity and Potential
Avishai Dekel, Guy Ishai, Aaron A. Dutton +1
We present a useful function for describing the profiles of dark-matter haloes with a varying asymptotic inner slope -α, ranging from a cusp to a core, where the profiles of densit…
