Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation
cosmology: large-scale structure of Universe, galaxies: clusters: general, meth- ods: N-body simulations
2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
The luminosities of the brightest cluster galaxies and brightest satellites in SDSS groups
galaxies: luminosity function
2011/10/11
We show that the distribution of luminosities of Brightest Cluster Galaxies, in two SDSS-based group catalogs, suggests that BCG luminosities are just the statistical extremes of the group galaxy lumi...
Galaxy-galaxy lensing constraints on the relation between baryons and dark matter in galaxies in the Red Sequence Cluster Survey 2
gravitational lensing: weak - galaxies: formation - galaxies: halos
2011/10/12
We present the results of a study of weak gravitational lensing by galaxies using imaging data that were obtained as part of the second Red Sequence Cluster Survey (RCS2). In order to compare to the b...
