The radio galaxy 1138−262 at z=2.2: a giant elliptical galaxy at the center of a proto-cluster?
We present a detailed observational study of a remarkable radio galaxy at a redshift of z = 2.2: 1138-262. This objectwas selected fromour compendiumof ultra steep spectrum radio sources on the basis of its distorted radio morphology. High resolution VLA radio observations show that the radio source consists of a series of knots and jet-like protrusions, with a sharp bend, strongly suggesting t...
متن کاملThe 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 کاملThe Xmm Cluster Survey : a Massive Galaxy Cluster at Z = 1 . 45
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 کاملVlt and Acs Observations of Rdcs J1252.9-2927: Dynamical Structure and Galaxy Populations in a Massive Cluster at Z=1.237
We present results from an extensive spectroscopic survey, carried out with VLT FORS, and from an extensive multiwavelength imaging data set from the HST Advanced Camera for Surveys and ground based facilities, of the cluster of galaxies RDCS J1252.9-2927. We have spectroscopically confirmed 38 cluster members in the redshift range 1.22 < z < 1.25. A cluster median redshift of z = 1.237 and a r...
متن کاملA MASSIVE, DISTANT PROTO-CLUSTER AT z = 2.47 CAUGHT IN A PHASE OF RAPID FORMATION?
Numerical simulations of cosmological structure formation show that the universe’s most massive clusters, and the galaxies living in those clusters, assemble rapidly at early times ( z 2.5 4 < < ). While more than 20 proto-clusters have been observed at z 2 based on associations of 5–40 galaxies around rare sources, the observational evidence for rapid cluster formation is weak. Here we repor...
