An Optical Group Catalogue to Z = 1 from the Zcosmos 10k Sample
We present a galaxy group catalogue spanning the redshift range 0.1 . z . 1 in the ∼ 1.7 deg COSMOS field, based on the first ∼ 10, 000 zCOSMOS spectra. The performance of both the Friendsof-Friends (FOF) and Voronoi-Delaunay-Method (VDM) approaches to group identification has been extensively explored and compared using realistic mock catalogues. We find that the performance improves substanti...
متن کاملK+a galaxies in the zCOSMOS survey*
Aims. The identities of the main processes triggering and quenching star-formation in galaxies remain unclear. A key stage in evolution, however, appears to be represented by post-starburst galaxies. To investigate the prevalence of these galaxies and their impact on galaxy evolution in general, we initiated a multiwavelength study of galaxies with k + a spectral features in the well-studied CO...
متن کاملThe 10k Zcosmos: Morphological Transformation of Galaxies in the Group
We study the evolution of galaxies inside and outside of the group environment since z = 1 using a large well defined set of groups and galaxies from the zCOSMOS-bright redshift survey in the COSMOS field. The fraction of galaxies with early-type morphologies increases monotonically with MB luminosity and stellar mass and with cosmic epoch. It is higher in the groups than elsewhere, especially ...
متن کاملThe UZC-SSRS2 Group Catalog
We apply a friends-of-friends algorithm to the combined UZC and SSRS2 redshift surveys to construct a catalog of 1168 groups of galaxies; 411 of these groups have 5 or more members within the redshift survey. The group catalog covers 4.69 steradians and all groups exceed the number density contrast threshold, δρ/ρ = 80. We demonstrate that the groups catalog is homogeneous across the two underl...
متن کاملThe Molonglo Reference Catalog 1-jy Radio Source Survey Iv: Optical Spectroscopy of a Complete Quasar Sample
Optical spectroscopic data are presented here for quasars from the Molonglo Quasar Sample (MQS), which forms part of a complete survey of 1-Jy radio sources from the Molonglo Reference Catalogue. The combination of low-frequency selection and complete identifications means that the MQS is relatively free from the orientation biases which affect most other quasar samples. To date, the sample inc...
