Evolution of the Dark Matter Phase-Space Density Distributions of LCDM Halos
Ileana Vass, Monica Valluri, Andrey Kravtsov +1
We study the evolution of phase-space density during the hierarchical structure formation of LCDM halos. We compute both a spherically-averaged surrogate for phase-space density (Q…
On relaxation processes in collisionless mergers
Monica Valluri, Ileana M. Vass, Stelios Kazantzidis +2
We analyze N-body simulations of halo mergers to investigate the mechanisms responsible for driving mixing in phase-space and the evolution to dynamical equilibrium. We focus on mi…
The Fundamental Properties of Dwarf Elliptical Galaxies in Clusters
Rafael Guzman, Alister W. Graham, Ana Matkovic +3
We present preliminary results of an extensive study of the fundamental properties of dwarf elliptical galaxies (dEs) in the Coma cluster. Our study will combine HST surface photom…
Transient chaos and resonant phase mixing in violent relaxation
Henry E. Kandrup, Ileana M. Vass, Ioannis V. Sideris
This paper explores how orbits in a galactic potential can be impacted by large amplitude time-dependences of the form that one might associate with galaxy or halo formation or str…
