Testing warm dark matter with kinematics of the smallest galaxies
M. Sten Delos, Niusha Ahvazi, Andrew Benson
Every dark matter halo forms with a density cusp at its center. For warm dark matter (WDM), these prompt cusps can be massive enough to influence the kinematics…
Role of prompt cusps in driving the core collapse of SIDM halos
Vinh Tran, Daniel Gilman, M. Sten Delos +4
Prompt cusps (PCs) form from the direct collapse of overdensities in the early Universe, reside at the center of every dark matter halo, and have density profiles steeper than $r^{…
Growth of Structure in Multi-species Wave Dark Matter
Mustafa A. Amin, M. Sten Delos
We explore the growth of structure in multi-species wave (and particle) dark matter. We derive the evolution of the power spectrum of total density contrasts for an arbitrary numbe…
Multi-species Dark Matter with Warmth and Randomness
Mustafa A. Amin, M. Sten Delos, Kaixin Yang
We present a general analytic framework for the evolution of cosmic structure in multi-species dark matter models that simultaneously incorporates finite velocity dispersion and Po…
The cusp-halo relation
M. Sten Delos
Simulations have established that each halo of collisionless dark matter is expected to contain a density cusp at its center. This prompt cusp is a relic of the hal…
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…
