Pre-Processing and Post-Processing in Group-Cluster Mergers [PDF]
, 2013 Galaxies in clusters are more likely to be of early type and to have lower star formation rates than galaxies in the field. Recent observations and simulations suggest that cluster galaxies may be `pre-processed' by group or filament environments and ...

The origin of the X-ray, radio and H I structures in the NGC 5903 galaxy group [PDF]
, 2017 The NGC 5903 galaxy group is a nearby (~30 Mpc) system of ~30 members, dominated by the giant ellipticals NGC 5903 and NGC 5898. The group contains two unusual structures, a ~110 kpc long HI filament crossing NGC 5903, and a ~75 kpc wide diffuse, steep ...

Galaxy Groups at Intermediate Redshift [PDF]
The Astrophysical Journal, 2001 Galaxy groups likely to be virialized are identified within the CNOC2 intermediate redshift galaxy survey using an iterative method. The number-velocity dispersion relation is in agreement with the low-mass extrapolation of the cluster normalized Press-Schechter function.

Constraints on the dynamical evolution of the galaxy group M81 [PDF]
, 2017 According to the standard model of cosmology, galaxies are embedded in dark matter halos which are made of particles beyond the standard model of particle physics, thus extending the mass and the size of the visible baryonic matter by typically two ...

The Centaurus Group and the Outer Halo of NGC 5128: Are they Dynamically Connected? [PDF]
, 2006 NGC 5128, a giant elliptical galaxy only $\sim 4$ Mpc away, is the dominant member of a galaxy group of over 80 probable members. The Centaurus group provides an excellent sample for a kinematic comparison between the halo of NGC 5128 and its surrounding

Probing the intra-group medium of a z = 0.28 galaxy group [PDF]
, 2016 We present new MUSE observations of a galaxy group probed by a background quasar. The quasar sightline passes between multiple z = 0.28 galaxies, whilst showing at the same redshift low-ionized metal line species, including Ca II, Mg I, Mg II and Fe II ...
