The radial structure of galaxy groups and clusters [PDF]

open access: greenMonthly Notices of the Royal Astronomical Society, 2003
Simple self-consistent models of galaxy groups and clusters are tested against the re-sults of high-resolutionadiabatic gasdynamicalsimulations.

The cosmological constant derived via galaxy groups and clusters [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The common nature of dark matter and dark energy is argued in Gurzadyan (Eur Phys J Plus 134:14, 2019) based on the approach that the cosmological constant $$\varLambda $$ Λ enters the weak-field General Relativity following from Newton theorem on the ...

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

open access: bronze, 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

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

open access: yesFrontiers 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.

Erratum: The XMM Large-Scale Structure survey: an initial sample of galaxy groups and clusters to a redshift z < 0.6 [PDF]

open access: bronze, 2005
We present X-ray and optical spectroscopic observations of 12 galaxy groups and clusters identified within the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey.

Dust accretion and destruction in galaxy groups and clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
We examine the dust distribution around a sample of 70000 low-redshift galaxy groups and clusters derived from the Sloan Digital Sky Survey (SDSS). By correlating spectroscopically identified background quasars with the galaxy groups, we obtain the ...

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

open access: yesAdvances 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]

open access: bronze, 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 ...

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

open access: bronze, 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 ...

Ram pressure profiles in galaxy groups and clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2011
Using a hybrid method that combines non-radiative hydrodynamical simulations with a semi-analytic model of galaxy formation, we determine the ram pressure experienced by galaxies in haloes with virial masses 12.5 ≤ log (M200/ h-1 M⊙) < 15.35 as a ...
