"Escaping From Galaxy Clusters" Abstract:As the largest bound objects in the Universe, galaxy clusters provide us an opportunity to observe galaxies escaping their gravitational potential wells at tremendous speeds. In simulated Universes, we know that bound gravitational tracers (like dark matter particles) fill their radius/velocity phase-spaces with a trumpet-like design. Caustic edges in these phase-space […]
