Galaxy groups in the 2dF redshift survey: Effects of Environment on Star Formation
TL;DR: In this article, the authors estimate the fraction of star forming galaxies in a catalogue of groups, constructed from the 2dF galaxy redshift survey by Merch\'an & Zandivarez.
Galaxy groups in the 2dF Galaxy Redshift Survey: luminosity and mass statistics
TL;DR: In this paper, the luminosity functions for different subsets of galaxies in groups were estimated using a Schechter function with parameters M ∗ 5 log(h) = 19.90 ± 0.03 and � = 1.13 ± 1.02.

Galaxy groups in the 2dF redshift survey: Galaxy Spectral Type Segregation in Groups
TL;DR: In this paper, the relative fraction of galaxies with different spectral types in groups is analyzed as a function of projected local galaxy density and the group-centric distance, showing a clear distinction between high virial mass groups and less massive ones.

The dynamical state of galaxy groups and their luminosity content
TL;DR: In this paper, the dependence of the luminosity function (LF) of galaxies in groups on group dynamical state was analyzed and the Anderson-Darling goodness-of-fit test was applied to distinguish between groups according to whether they have Gaussian or non-Gaussian velocity distributions.
Properties of groups of galaxies in the vicinity of massive clusters
TL;DR: In this paper, the authors analyzed the properties of groups of galaxies in the surroundings of clusters and found that properties such as velocity dispersion, internal energy (E) and virial radius of groups are affected by the proximity of massive hosts.
