Ultra-Light Dark Matter Simulations and Stellar Dynamics: Tension in Dwarf Galaxies for eV
Luca Teodori, Andrea Caputo, Kfir Blum
We present numerical simulations of dark matter and stellar dynamics in ultra light dark matter halos tailored to mimic dwarf galaxies. An important effect we observe is the dynami…
