Structural properties of central galaxies in groups and clusters [PDF]

open access: yesMonthly 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 ...

Physical Implications of the X-ray Properties of Galaxy Groups and Clusters [PDF]

open access: yes, 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 ...

Galaxy Superclusters Detected in the Modified PF-Catalog Using the FOF Method

open access: yesOpen Astronomy, 2011
The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters.

Shell-like structures in our cosmic neighbourhood

open access: yes, 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.

Entropy amplification from energy feedback in simulated galaxy groups and clusters [PDF]

open access: yes, 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).

Radio galaxy feedback in X-ray selected groups from COSMOS: the effect on the ICM [PDF]

open access: yes, 2010
We quantify the importance of the mechanical energy released by radio-galaxies inside galaxy groups. We use scaling relations to estimate the mechanical energy released by 16 radio-AGN located inside X-ray detected galaxy groups in the COSMOS field.

Galaxy pairs in the 2dF survey ¿ II. Effects of interactions on star formation in groups and clusters [PDF]

open access: yes, 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

First ranked galaxies in groups and clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1985
On montre que ces galaxies ne sont pas les membres extremes d'une population statistique mais qu'elles constituent plutot la queue d'une distribution ...

Mock Observations: Formation and Evolution of Diffuse Light in Galaxy Groups and Clusters in the IllustrisTNG Simulations

open access: yesThe Astrophysical Journal, 2023
In this paper, by analyzing mock images from the IllustrisTNG100-1 simulation, we examine the properties of diffuse light and compare them to those of central and satellite galaxies.
