The Spiderweb Galaxy : a Forming Massive Cluster Galaxy at Z ∼ 2
We present a deep image of the radio galaxy MRC 1138–262 taken with the Hubble Space Telescope (HST) at a redshift of z = 2.2. The galaxy is known to have properties of a cD galaxy progenitor and be surrounded by a 3 Mpc-sized structure, identified with a protocluster. The morphology shown on the new deep HST ACS image is reminiscent of a spider’s web. More than 10 individual clumpy features ar...

متن کاملXMM-Newton OBSERVES CLJ0152.7−1357: A MASSIVE GALAXY CLUSTER FORMING AT MERGER CROSSROADS AT Z = 0.83
We present an analysis of a 50 ks XMM-Newton observation of the merging galaxy cluster ClJ0152.7−1357 at z = 0.83. In addition to the two main subclusters and an infalling group detected in an earlier Chandra observation of the system, XMM-Newton detects another group of galaxies possibly associated with the cluster. This group may be connected to the northern subcluster by a filament of cool (...

We report the discovery of XMMXCS J2215.9 1738, a massive galaxy cluster at , which was found z p 1.45 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 six galaxies within a ∼60 diameter region lie at . z p 1.45 0.01 Model fits to the X-ray spectra of the extended emission yield keV (90% c...

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 = ...
