Kinematics of the diffuse intragroup and intracluster light in groups and clusters of galaxies in the local universe within 100 Mpc distance [PDF]

Frontiers in Astronomy and Space Sciences, 2022
Nearly all intragroup (IGL) and intracluster light (ICL) comes from stars that are not bound to any single galaxy but were formed in galaxies and later unbound from them.

Density profiles of galaxy groups and clusters from SDSS galaxy–galaxy weak lensing [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
We present results of a measurement of the shape of the density profile of galaxy groups and clusters traced by 43 335 Luminous Red Galaxies (LRGs) with spectroscopic redshifts from the Sloan Digital Sky Survey (SDSS). The galaxies are selected such that

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

Reexamination of the Galaxy Formation–regulated Gas Evolution Model in Groups and Clusters [PDF]

, 2002
As an alternative explanation of the entropy excess and the steepening of the X-ray luminosity-temperature relation in groups and clusters, the galaxy formation-regulated gas evolution (GG) model proposed recently by Bryan makes an attempt to incorporate

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 ...

Galaxy and mass assembly (GAMA): the clustering of galaxy groups [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We explore the clustering of galaxy groups in the Galaxy and Mass Assembly (GAMA) survey to investigate the dependence of group bias and profile on separation scale and group mass. Due to the inherent uncertainty in estimating the group selection function, and hence the group autocorrelation function, we instead measure the ...

Properties of Fossil Groups of Galaxies

Universe, 2021
We review the formation and evolution of fossil groups and clusters from both the theoretical and the observational points of view. In the optical band, these systems are dominated by the light of the central galaxy.
