GMOS spectroscopy of galaxies in a z 0.8 structure
Abstract
The largest large-scale structures (super-LSSs, SLSSs) provide essential tests for models of structure formation and allow the very efficient study of large numbers of galaxies, clusters and other mass markers such as quasars. The epoch z 1 has emerged as ``special", from both observational and theoretical arguments, for the evolution of galaxies and for the assembly of galaxy clusters. In a sky area extending several degrees and through deep multicolor imaging, we have found 'superposed' SLSS > 20-30 Mpc at both z 0.8 and z 1.2 (Haines, Campusano & Clowes, 2004) . In this paper we present the results of the follow-up spectroscopy of a 5'x5' region targeting the z 0.8 structure using GMOS on Gemini South.
