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 ...

THE GALAXY CONTENT OF SDSS CLUSTERS AND GROUPS [PDF]

open access: bronzeThe Astrophysical Journal, 2009
Imaging data from the Sloan Digital Sky Survey are used to characterize the population of galaxies in groups and clusters detected with the MaxBCG algorithm.

Individual and Group Galaxies in CNOC1 clusters [PDF]

open access: bronzeAstrophys.J.698:83-98,2009, 2009
Using wide-field $BVR_cI$ imaging for a sample of 16 intermediate redshift ($0.17 < z < 0.55$) galaxy clusters from the Canadian Network for Observational Cosmology (CNOC1) Survey, we investigate the dependence of cluster galaxy populations and their evolution on environment.

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 ...

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 ...

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 and Mass Assembly (GAMA): the clustering of galaxy groups [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
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 auto-correlation function, we instead measure the projected galaxy--group ...

Integrated HI emission in galaxy groups and clusters [PDF]

open access: yes, 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 ...
