cds-question@unistra.frgalaxy-clustersredshiftedvisible-astronomysloan-photometryradio-galaxiesWe present an in-depth analysis of the Butcher-Oemler cluster A2111, including new optical spectroscopy plus a deep Very Large Array (VLA) radio continuum observation. These are combined with optical imaging from the Sloan Digital Sky Survey (SDSS) to assess the activity and properties of member galaxies. Prior X-ray studies have suggested A2111 to be a head-on cluster merger, a dynamical state that might be connected to the high level of activity inferred from its blue fraction. We are able to directly assess this claim, using our spectroscopic data to identify 95 cluster members among 196 total galaxy spectra. We are able to detect 175 optical sources from the SDSS in our VLA radio data, of which 35 have redshift information.2006AJ....131.2426Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2426CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org : SDSS Home PageJ/ApJS/146/267 : Very rich Abell clusters radio analysis (Morrison+ 2003)J/ApJS/122/51 : Spectroscopic catalog of 10 rich galaxy clustersJ/AJ/118/625 : Radio sources in Abell 2125 and 2645 (Dwarakanath+ 1999)J/AJ/116/1529 : cD clusters of galaxies.
