The XMM Cluster Survey : A Massive Galaxy
We report the discovery of XMMXCS J2215.9-1738, a massive galaxy cluster at z = 1.45, which was found in the XMM Cluster Survey. The cluster candidate was initially identified as an extended X-ray source in archival XMM data. Optical spectroscopy shows that 6 galaxies within a ∼60 arcsec diameter region lie at z = 1.45 ± 0.01. Model fits to the X-ray spectra of the extended emission yield kT = ...

متن کاملCosmology with Gtc . a Combined Mm - Optical Galaxy Cluster Survey
The CMB Planck satellite (ESA) will provide a catalogue of ≈ 30000 galaxy clusters (Sunyaev-Zel'dovich effect) between redshift 0 and ≈ 2-3 (depending on the cosmological model). This hughe catalogue of clusters will allow detailed studies of the evolution of the cluster population with redshift which will constrain the cosmological model. The identification of the high redshift clusters should...
متن کاملGalaxy-cluster gas-density distributions of the representative XMM-Newton cluster structure survey (REXCESS)
We present a study of the structural and scaling properties of the gas distributions in the intracluster medium (ICM) of 31 nearby (z < 0.2) clusters observed with XMM-Newton, which together comprise the Representative XMM-Newton Cluster Structure Survey (REXCESS). In contrast to previous studies, this sample is unbiased with respect to X-ray surface brightness and cluster dynamical state, and ...
