Exploring diffuse radio emission in galaxy clusters and groups with uGMRT and SKA [PDF]
Journal of astrophysics and astronomy, 2022 Diffuse radio emission has been detected in a considerable number of galaxy clusters and groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic particles in the large scale structure of the Universe.

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 ...

The XMM Large-Scale Structure survey: an initial sample of galaxy groups and clusters to a redshift z < 0.6★ [PDF]
, 2005 We present X-ray and optical spectroscopic observations of 12 galaxy groups and clusters identified within the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey.

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.

Triggering of merger‐induced starbursts by the tidal field of galaxy groups and clusters [PDF]
, 2007 Star formation in galaxies is for a part driven by galaxy mergers. At low redshift, star formation activity is low in high-density environments like groups and clusters, and the star formation activity of galaxies increases with their isolation.

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.

Entropy Evolution in Galaxy Groups and Clusters: a Comparison of External and Internal Heating [PDF]
, 2001 The entropy in hot, X-ray-emitting gas in galaxy groups and clusters is a measure of past heating events, except for the entropy lost by radiation from denser regions.

Implications of the remarkable homogeneity of galaxy groups and clusters [PDF]
, 2009 We measure the diversity of galaxy groups and clusters with mass M > 1013 h−1 M⊙, in terms of the star formation history of their galaxy populations, for the purpose of constraining the mass scale at which environmentally important processes play a role ...

Velocity-dependent self-interacting dark matter from groups and clusters of galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We probe the self-interactions of dark matter with relaxed galaxy groups and clusters using observational data from strong and weak lensing and stellar kinematics.

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 ...
