TL;DR: In this paper, a detailed comparison of the substructure properties of a single Milky Way sized dark matter halo from the Aquarius suite at five different resolutions, as identified by a variety of different (sub)halo finders for simulations of cosmic structure formation, is presented.
Galaxy Groups in the SDSS-DR3
TL;DR: In this article, a new sample of galaxy groups identified in the Sloan Digital Sky Survey Data Release 3 is presented, with 10864 galaxy groups with at least four members, and the final group sample has a mean redshift of 0.1 and median velocity dispersion of $230 km s^{-1}$.

Galaxy groups in the 2dF redshift survey: The catalogue
TL;DR: In this paper, the authors constructed a galaxy groups catalogue from the public 100k data release of the 2dF galaxy redshift survey using a slightly modified version of the group finding algorithm developed by Huchra & Geller.

On the Luminosity Function of Galaxies in Groups in the Sloan Digital Sky Survey
TL;DR: In this paper, the authors used galaxy groups identified in the fourth data release of the Sloan Digital Sky Survey (SDSS) to compute the luminosity function for several subsamples of galaxies in groups.

TL;DR: In this paper, a comparison of spin distributions of subhaloes found associated with a host halo was performed in two cosmological simulation families of Milky Way-like galaxies, namely the Aquarius and GHALO simulations.
