TL;DR: In this article, the authors present a new model to describe the galaxy-dark matter connection across cosmic time, which unlike the popular subhalo abundance matching technique is selfconsistent in that it takes account of the facts that subhalos are accreted at different times, and the properties of satellite galaxies may evolve after accretion.

TL;DR: In this paper, the alignment between the orientation of the central galaxy (defined as the brightest group member) and the distribution of satellite galaxies was examined. But the alignment on scales smaller than the halo virial radius was not considered.

TL;DR: In this article, the authors investigated the incidence of major mergers creating massive (Mstar > 10 11 M� ) galaxies in present-day (z ≤ 0.12) groups and clusters using a volume-limited sample of 845 groups with dark matter halo masses above 2.5 × 10 13 M �.

TL;DR: In this paper, the authors used the predicted two-dimensional correlation function xi(r(p), pi) to link the distribution of galaxies to that of dark matter haloes by considering halo occupation numbers as a function of galaxy luminosity and type.

TL;DR: In this article, it was shown that the inner r -1 profile of CDM haloes is a natural result of hierarchical mass assembly with an initial phase of rapid accretion and the concentration of a halo is determined by the fraction of mass that is accreted during the fast-accretion phase.
