Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites
Ethan O. Nadler, Mustafa A. Amin, Risa H. Wechsler +3
We generalize lower limits on the dark matter (DM) particle mass derived from Milky Way (MW) satellite galaxy abundances to scenarios in which DM is an ultralight scalar field…

Structure Formation with Warm White Noise: Effects of Finite Number Density and Velocity Dispersion in Particle and Wave Dark Matter
Mustafa A. Amin, M. Sten Delos, Mehrdad Mirbabayi
We investigate the evolution of density perturbations in dark matter, including the new combined effects of finite number density and non-zero velocity dispersion. Using a truncate…
