Ram pressure profiles in galaxy groups and clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 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

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

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.

Implications of the remarkable homogeneity of galaxy groups and clusters [PDF]

, 2010
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 ...

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 ...

Dark Matter in Groups and Clusters of Galaxies [PDF]

International Astronomical Union Colloquium, 2000
AbstractWe compare the characteristics of stellar populations with those of dark halos. Dark matter around galaxies, and in groups, clusters and voids is discussed. Modern data suggest that the overall density of matter in the Universe is ΩM = 0.3 ± 0.1, about 80 % of this matter is nonbaryonic dark matter, and about 20 % is baryonic, mostly in the ...
