Kinematic analysis of a sample of X-ray luminous distant galaxy clusters. The - relation in the universe
Alessandro Nastasi, Hans Böhringer, Rene Fassbender +11
Observations and cosmological simulations show galaxy clusters as a family of nearly self-similar objects with properties that can be described by scaling relations as a function o…
Finding Rare AGN: XMM-Newton and Chandra Observations of SDSS Stripe 82
Stephanie M. LaMassa, C. Megan Urry, Nico Cappelluti +15
We have analyzed the {\it XMM-Newton} and {\it Chandra} data overlapping 16.5 deg of Sloan Digital Sky Survey Stripe 82, including 4.6 deg of proprietary {\it X…
Probing the evolution of the substructure frequency in galaxy clusters up to z~1
A. Weißmann, H. Böhringer, G. Chon
Context. Galaxy clusters are the last and largest objects to form in the standard hierarchical structure formation scenario through merging of smaller systems. The substructure fre…
Suzaku observations of the low surface brightness cluster A76
N. Ota, Y. Fujino, Y. Ibaraki +2
Context: We present results of Suzaku observations of a nearby galaxy cluster A76 at z=0.0395. This cluster is characterized by extremely low X-ray surface brightness and is hereaf…
Dust-obscured star-formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z=1.4
J. S. Santos, B. Altieri, P. Popesso +17
Star-formation in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region. Indications of a revers…
The X-ray Properties of Optically Selected Clusters of Galaxies
Amalia K. Hicks, Gabriel W. Pratt, Megan Donahue +7
We present the results of Chandra and Suzaku X-ray observations of nine moderate-redshift (0.16 < z < 0.42) clusters discovered via the Red-sequence Cluster Survey (RCS). Surface b…
