Star Stream Velocity Distributions in CDM and WDM Galactic Halos
Raymond G. Carlberg, Adrian Jenkins, Carlos S. Frenk +1
The dark matter subhalos orbiting in a galactic halo perturb the orbits of stars in thin stellar streams. Over time the random velocities in the streams develop non-Gaussian wings.…
