The radial structure of galaxy groups and clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 Simple self-consistent models of galaxy groups and clusters are tested against the results of high-resolution adiabatic gasdynamical simulations. We investigate two models based on the existence of a 'universal' dark matter density profile and two ...

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

Dust accretion and destruction in galaxy groups and clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We examine the dust distribution around a sample of 70,000 low redshift galaxy groups and clusters derived from the Sloan Digital Sky Survey. By correlating spectroscopically identified background quasars with the galaxy groups we obtain the relative ...

Observational Mass-to-Light Ratio of Galaxy Systems: from Poor Groups to Rich Clusters [PDF]
, 2001 We study the mass-to-light ratio of galaxy systems from poor groups to rich clusters, and present for the first time a large database for useful comparisons with theoretical predictions.

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

Integrated HI emission in galaxy groups and clusters [PDF]
, 2017 The integrated HI emission from hierarchical structures such as groups and clusters of galaxies can be detected by FAST at intermediate redshifts. Here we propose to use FAST to study the evolution of the global HI content of clusters and groups over ...

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

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 ...
