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 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.

Galaxy groups in the 2dF Galaxy Redshift Survey: effects of environment on star formation
TL;DR: In this paper, the authors estimate the fraction of star-forming galaxies in a catalogue of groups, constructed from the 2dF Galaxy Redshift Survey by Merchan & Zandivarez.

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, and a clear distinction between high virial mass groups (MV≳ 1013.5 M⊙) and the less massive ones was made.
Redshift-Space Distortions of Group and Galaxy Correlations in the Updated Zwicky Catalog
TL;DR: In this paper, the two-point correlation function for galaxies and groups of galaxies selected using three-dimensional information from the Updated Zwicky Galaxy Catalog (UZC) was computed for the redshift-space distortion of the correlation function, induced by pairwise group peculiar velocities.
