Chandra Studies of the X-ray Gas Properties of Fossil Systems
, 2015 We study ten galaxy groups and clusters suggested in the literature to be "fossil system (FS)" based on \chandra\ observations. According to the $M_{500}-T$ and $L_{\rm X}-T$ relations, the gas properties of FSs are not physically distinct from ordinary ...

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.

Physical Implications of the X-ray Properties of Galaxy Groups and Clusters [PDF]
, 2001 Within the standard framework of structure formation, where clusters and groups of galaxies are built up from the merging of smaller systems, the physical properties of the intracluster medium, such as the gas temperature and the total X-ray luminosity ...

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.

Explaining the entropy excess in clusters and groups of galaxies without additional heating [PDF]
, 2000 The X-ray luminosity and temperature of clusters and groups of galaxies do not scale in a self-similar manner. This has often been interpreted as a sign that the intracluster medium has been substantially heated by non-gravitational sources.

Entropy amplification from energy feedback in simulated galaxy groups and clusters [PDF]
, 2005 We use hydrodynamical simulations of galaxy clusters and groups to study the effect of pre–heating on the entropy structure of the intra–cluster medium (ICM).

Galaxy pairs in the 2dF survey ¿ II. Effects of interactions on star formation in groups and clusters [PDF]
, 2004 We assess the effects of galaxy-galaxy interactions on star formation (SF) by analysing pairs in groups and clusters of galaxies with virial masses in the range 10 13 -10 15 M ○. extracted from the 2dF Galaxy Redshift Survey (2dFGRS). We find that galaxy

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 ...

The properties of the hot gas in galaxy groups and clusters from ID hydrodynamical simulations - I. Cosmological infall models [PDF]
, 1997 We report the results of 1-D hydrodynamical modelling of the evolution of gas in galaxy clusters. We have incorporated many of the effects missing from earlier 1-D treatments: improved modelling of the dark matter and galaxy distributions, cosmologically
