A lensed radio jet at milli-arcsecond resolution II: Constraints on fuzzy dark matter from an extended gravitational arc
Devon M. Powell, Simona Vegetti, J. P. McKean +4
Using a single gravitational lens system observed at milli-arcsecond resolution with very long baseline interferometry (VLBI), we place a lower bound on the mass of the…
Reducing Noise in Cosmological N-body Simulations with Neutrinos
Arka Banerjee, Devon Powell, Tom Abel +1
We present a new method for generating initial conditions for numerical cosmological simulations in which massive neutrinos are treated as an extra set of N-body (collisionless) pa…
The Doppler effect on indirect detection of dark matter using dark matter only simulations
Devon Powell, Ranjan Laha, Kenny C. Y. Ng +1
Indirect detection of dark matter is a major avenue for discovery. However, baryonic backgrounds are diverse enough to mimic many possible signatures of dark matter. In this work,…
Voids in cosmological simulations over cosmic time
Radosław Wojtak, Devon Powell, Tom Abel
We study evolution of voids in cosmological simulations using a new method for tracing voids over cosmic time. The method is based on tracking watershed basins (contiguous regions…
