Evolution of the Phase-Space Density of Dark Matter Halos and Mixing Effects in Merger Events
Sébastien Peirani, Fabrice Durier, José Antonio De Freitas Pacheco
Cosmological N-body simulations were performed to study the evolution of the phase-space density Q = rho/sigma^3 of dark matter halos. No significant differences in the scale relat…
Mass Determination of Groups of Galaxies: Effects of the Cosmological Constant
Sébastien Peirani, José Antonio De Freitas Pacheco
The spherical infall model first developed by Lemaître and Tolman was modified in order to include the effects of a dark energy term. The resulting velocity-distance relation was e…
Indirect Search for Dark Matter
José Antonio De Freitas Pacheco, Sébastien Peirani
Possible dark matter candidates are reviewed as well as indirect search methods based on annihilation or decay channels of these particles. Neutralino is presently the best particl…
