cds-question@unistra.frgalaxy-clustersgalaxiesphotometryradial-velocityThe connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still being debated. We aim to obtain new insights into the internal dynamics of Abell 959, showing evidence of a diffuse radio source, analyzing velocities and positions of member galaxies. Our analysis is based on redshift data for 107 galaxies in the cluster field acquired at the Telescopio Nazionale Galileo. We also use photometric data from the Sloan Digital Sky Survey (Data Release 6). We combine galaxy velocities and positions to select 81 galaxies recognized as cluster members and determine global dynamical properties. We analyze the cluster searching for substructures by using the weighted gap analysis, the KMM method and the Dressler-Shectman statistics. We also study the 2D galaxy distribution in the field of the cluster. We compare our results with those from X-ray and gravitational lensing analyses.2009A&A...495...15Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/495/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/282 : The SDSS Photometric Catalog, Release 6 (Adelman-McCarthy+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/495/15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/495/15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/495/15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/495/15https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/495/15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/495/15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/495/15/table1 (Velocity catalog of 107 spectroscopically measured galaxies in the field of A959)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/495/15/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/495/15/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/495/15/table1?GETtext/xml+votable180.050000true154.22162559.53222220.0055555555555555566/7448https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/495/15?format=asciiOpticaldefaultJ/A+A/495/15/table1Velocity catalog of 107 spectroscopically measured galaxies in the field of A959recnoRecord number assigned by the VizieR team.
