cds-question@unistra.frgalaxy-clustersredshiftedspectroscopyWe present a spectrophotometric analysis of the galaxy population in the area of the merging cluster Abell 2384 at z=0.094. We investigate the impact of the complex cluster environment on galaxy properties, such as colour, morphology, and star formation rate. We combined multi-object spectroscopy from the 2dF and EFOSC2 spectrographs with optical imaging of the inner 30x30-arcmin of A2384 taken with the ESO Wide Field Imager. We carried out a kinematical analysis using the EMMIX algorithm and biweight statistics. We address the possible presence of cluster substructures with the Dressler-Shectman test. Cluster galaxies are investigated with respect to [OII] and H{alpha} equivalent width. Galaxies covered by our optical imaging observations are additionally analysed in terms of colour, star formation rate, and morphological descriptors, such as Gini coefficient and M20 index. We study cluster galaxy properties as a function of clustercentric distance and investigate the distribution of various galaxy types in colour-magnitude and physical space.2014A&A...570A..40Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/570/A40CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/525/A79 : Velocities in three Abell clusters (Maurogordato+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/570/A40https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/570/A40http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/570/A40https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/570/A40https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/570/A40http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/570/A40GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/570/A40/table4 (List of spectra for 305 galaxies observed with the 2dF device at the AAO in June 2005)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/570/A40/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/570/A40/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/570/A40/table4?GETtext/xml+votable180.050000true327.951-18.59840.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/570/A405/12122 6/48482-48483 48492 48494https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/570/A40?format=asciiOpticaldefaultJ/A+A/570/A40/table4List of spectra for 305 galaxies observed with the 2dF device at the AAO in June 2005recnoRecord number assigned by the VizieR team.
