The APM cluster - galaxy cross - correlation function : Constraints on Ω and galaxy bias
We estimate the cluster-galaxy cross-correlation function (ξcg), from the APM galaxy and galaxy cluster surveys. We obtain estimates both in real space from the inversion of projected statistics and in redshift space using the galaxy and cluster redshift samples. The amplitude of ξcg is found to be almost independent of cluster richness. At large separations, r ∼> 5 h Mpc ( h = H0/100km s , whe...
متن کاملThe Spiderweb Galaxy: a Forming Massive Cluster Galaxy
We present a deep image of the radio galaxy MRC 1138 262 taken with the Hubble Space Telescope (HST) at a redshift of . The galaxy is known to have properties of a cD galaxy progenitor and be surrounded z p 2.2 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 a...
متن کاملThe Xmm Cluster Survey : a Massive Galaxy Cluster At
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...
متن کاملThe XMM Cluster Survey : A Massive Galaxy Cluster
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 کاملGlobular Cluster Systems in the Hydra I Galaxy Cluster
In this contribution, first results of deep VLT photometry (V,I) in the central region of the Hydra I galaxy cluster are presented. Many star clusters have been identified not only around several earlytype galaxies, but also in the intra-cluster field, as far as 250 kpc from the cluster center. Outside the bulges of the central galaxies NGC 3311 and NGC 3309, the intra-cluster globular cluster ...
