Galaxies living in rich environments are suffering different perturbations able to drastically
affect their evolution. Among these, ram pressure stripping, ie the pressure exerted by the …

Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

Satellite galaxies in groups and clusters are more likely to have low star formation rates
(SFRs) and lie on the 'red sequence'than central ('field') galaxies. Using galaxy group/cluster …

The dark matter that appears to be gravitationally dominant on all scales larger than galactic
cores may consist of axions, stable photinos, or other collisionless particles whose velocity …

We conduct a comprehensive analysis of the relationship between central galaxies and their
host dark matter halos, as characterized by the stellar mass–halo mass (SM–HM) relation …

We review the formalism and applications of non-linear perturbation theory (PT) to
understanding the large-scale structure of the Universe. We first discuss the dynamics of …

We examine the temperature history of gas accreted by forming galaxies in smoothed
particle hydrodynamics simulations. About half of the gas follows the track expected in the …

We study dark matter halo density profiles in a high-resolution N-body simulation of a ΛCDM
cosmology. Our statistical sample contains∼ 5000 haloes in the range 1011− 1014 h− 1 …

Using galaxy group/cluster catalogues created from the Sloan Digital Sky Survey Data
Release 7, we examine in detail the specific star formation rate (SSFR) distribution of …

We present an estimate of the global budget of baryons in all states, with conservative
estimates of the uncertainties, based on all relevant information we have been able to …
