Late-Time Oscillating Quintessence in Light of DESI
Jun-Qian Jiang, Mustafa A. Amin, Arman Shafieloo
Recent DESI baryon acoustic oscillation measurements, especially when combined with Type Ia supernova and CMB data, sharpen the case for possible low-redshift dynamics in the dark…

Early Growth of Structure in Warm Wave Dark Matter
Mustafa A. Amin, Simon May, Mehrdad Mirbabayi
We explore the growth of structure in wave-like dark matter models, where the field and density spectra are peaked at sub-horizon wavenumbers. Starting with the Schrödinger-Poisson…

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…
