Cluster detection from surface-brightness fluctuations in SDSS data [PDF]
, 2001 Galaxy clusters can be detected as surface brightness enhancements in smoothed optical surveys. This method does not require individual galaxies to be identifiable, and enables clusters to be detected out to surprisingly high redshifts, as recently ...

Dynamical segregation of galaxies into groups and clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We have performed a systematic analysis of the dynamics of different galaxy populations in galaxy groups from the 2dFGRS. For this purpose we have combined all the groups into a single system, where velocities v and radius r are expressed adimensionally.

The Environment of ``E+A'' Galaxies [PDF]
, 1995 The violent star formation history of ``E+A'' galaxies and their detection almost exclusively in distant clusters is frequently used to link them to the ``Butcher-Oemler effect'' and to argue that cluster environment influences galaxy evolution.

AGN Feedback in Groups and Clusters of Galaxies
, 2022 AGN feedback stands for the dramatic impact that a SMBH can make on its environment. It has become an essential element of models that describe the formation and evolution of baryons in massive virialized halos. The baryons' radiative losses in the cores of these halos might lead to massive cooling and vigorous star formation on the order of 10-1000 ...

MORPHOLOGICAL TYPES OF 254 RICH PF GALAXY CLUSTERS
Odessa Astronomical Publications, 2014 We determined the morphological types for 254 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The data set contains the PF galaxy clusters, which have no ACO coinciding ones.

X-RAY EMISSION AND ORIENTATION OF SELECTED PF GALAXY CLUSTERS
Odessa Astronomical Publications, 2016 X-ray counterparts for 35 galaxy clusters contained in the PF catalogue of galaxy clusters and groups were found in XMM-Newton archive. 22 ones (all from ACO catalogue) have extended elliptic X-ray haloes appropriate for determination of orientation ...

Structural properties of central galaxies in groups and clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 Using a statistically representative sample of 911 central galaxies (CENs) from the Sloan Digital Sky Survey (SDSS) Data Release 4 group catalogue, we study how the structure (shape and size) of the first rank (by stellar mass) group and cluster members depends on (1) galaxy stellar mass (Mstar), (2) the global environment defined by the dark matter ...

Shell-like structures in our cosmic neighbourhood
, 2016 Signatures of the processes in the early Universe are imprinted in the cosmic web. Some of them may define shell-like structures characterised by typical scales.

Ram pressure profiles in galaxy groups and clusters [PDF]
, 2011 Using a hybrid method which combines non-radiative hydrodynamical simulations with a semi-analytic model of galaxy formation, we determine the ram pressure as a function of halocentric distance experienced by galaxies in haloes with virial masses 12.5
