The faint light in groups and clusters of galaxies [PDF]

Nature Astronomy, 2022
The diffuse light that spreads through groups and clusters of galaxies is made of free-floating stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds important clues for understanding the evolution of these large ...

Iron as a tracer in galaxy clusters and groups [PDF]

The Astrophysical Journal, 1997
Available X-ray data are collected and organized concerning the iron and gas content of galaxy clusters and groups, together with the optical luminosity, mass and iron abundance of cluster galaxies.

A Census of Baryons in Galaxy Clusters and Groups [PDF]

Proceedings of the International Astronomical Union, 2007
We determine the contribution of stars in galaxies, intracluster stars, and the intracluster medium to the total baryon budget in nearby galaxy clusters and groups. We find that the baryon mass fraction (f_b) within r500 is constant for systems with M500

Einstein observations of the Hydra A cluster and the efficiency of galaxy formation in groups and clusters

, 1990
The Einstein imaging proportional counter observations of the poor cluster of galaxies centered on the radio galaxy Hydra A are examined. From the surface brightness profile, it is found that the X-ray-emitting gas in the Hydra A cluster must be ...

Evidence for AGN Feedback in Galaxy Clusters and Groups [PDF]

Advances in Astronomy, 2012
The current generation of flagship X-ray missions, Chandra and XMM-Newton, has changed our understanding of the so-called “cool-core” galaxy clusters and groups.

The cosmological free-free signal from galaxy groups and clusters [PDF]

, 2010
Using analytical models and cosmological N-body simulations, we study the free-free radio emission from ionized gas in clusters and groups of galaxies. The results obtained with the simulations are compared with analytical predictions based on the mass ...

Galaxy evolution in groups and clusters: star formation rates, red sequence fractions and the persistent bimodality [PDF]

, 2012
Using galaxy group/cluster catalogues created from the Sloan Digital Sky Survey Data Release 7, we examine in detail the specific star formation rate (SSFR) distribution of satellite galaxies and its dependence on stellar mass, host halo mass and halo ...

Revisiting the Cooling Flow Problem in Galaxies, Groups, and Clusters of Galaxies [PDF]

The Astrophysical Journal, 2018
We present a study of 107 galaxies, groups, and clusters spanning ∼3 orders of magnitude in mass, ∼5 orders of magnitude in central galaxy star formation rate (SFR), ∼4 orders of magnitude in the classical cooling rate ( ) of the intracluster medium (ICM)

Diffuse Baryons in Groups and Clusters of Galaxies [PDF]

The Astrophysical Journal, 1998
To predict the X-ray observables associated to the diffuse baryons in clusters of galaxies, we develop a new physical approach to model such a hot intra-cluster plasma. Such approach is based on punctuated equilibria. and comprises the following blocks: Monte Carlo ``merging histories'' of dark matter potential wells; the central hydrostatic ...
