X-ray Selected Clusters of Galaxies
نویسنده
چکیده
Three topics will be presented in this paper: 1) study of the clusters and groups of galaxies found serendipitously in the North Ecliptic Pole (NEP) region of the ROSAT all-sky survey; 2) the highest redshift clusters found in the EMSS and the cosmological implications of their very existence; 3) the gravitational lensing in the EMSS X-ray selected clusters of galaxies observed by the Hubble Space Telescope.

Optical and X-ray Clusters as Tracers of the Supercluster-void Network. I Superclusters of Abell and X-ray Clusters
We study the distribution of X-ray selected clusters of galaxies with respect to superclusters determined by Abell clusters of galaxies and show that the distribution of X-ray clusters follows the supercluster-void network determined by Abell clusters. We find that in this network X-ray clusters are more strongly clustered than other clusters: the fraction of X-ray clusters is higher in rich su...
متن کاملWeak lensing observations of potentially X-ray underluminous galaxy clusters
Optically selected clusters of galaxies display a relation between their optical mass estimates and their X-ray luminosities LX that has a large scatter. A substantial fraction of optically selected clusters have LX estimates or upper limits significantly below the values expected from the LX-mass relation established for X-ray selected clusters, i.e., these clusters are X-ray underluminous for...

متن کاملICM properties and AGN distribution in high-z RCS clusters
Context. The study of the thermodynamical and chemical properties of the Intra Cluster Medium (ICM) in high redshift clusters of galaxies is a powerful tool to investigate the formation and evolution of large scale structures. Here we discuss the X–ray properties of clusters of galaxies optically selected in the Red–Sequence Cluster Survey (RCS) observed with the Chandra satellite, at redshifts...
متن کاملA Radio Survey of Seven Southern X-ray Luminous Clusters of Galaxies
The Australia Telescope Compact Array (ATCA) has been used at 1.38 and 2.38 GHz to survey seven southern Abell clusters of galaxies with high X-ray luminosities: A2746, A2837, A3126, A3216, A3230, A3827 and A3836. The clusters have also been surveyed at 0.843 GHz with the Molonglo Observatory Synthesis Telescope (MOST). We have listed a complete 1.38GHz sample of 149 radio sources within the Ab...
