cds-question@unistra.frgalaxy-clustersgalaxiesspectroscopyredshiftedWe present a detailed spatial and dynamical analysis of the central ~2.2Mpc(Ho=75km/s/Mpc) region of the galaxy cluster Abell 521 (z=0.247), based on 238 spectra (of which 191 new measurements) obtained at the 3.6m Telescope of the European Southern Observatory and at the Canada-France-Hawaii Telescope. From the analysis of the 125 galaxies that are confirmed members of the cluster, we derive a location ("mean" velocity) of C_BI_=74019^{+112}^_{-125}_km/s and detect a complex velocity distribution with high velocity scale ("dispersion", S_BI_=1325^{+145}^_{-100}_km/s), but clear departure from a single Gaussian component. When excluding a possible background group of four galaxies, the velocity dispersion remains still large (~1200 km/s).2003A&A...399..813Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/399/813CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/399/813https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/399/813http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/399/813https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/399/813https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/399/813http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/399/813GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/399/813/table10 (Radial velocities and spectral lines for 191 galaxies in A521)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/399/813/table10?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/399/813/table10?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/399/813/table10?GETtext/xml+votable180.050000true73.449625-10.18986670.0055555555555555566/22607https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/399/813?format=asciiOpticaldefaultJ/A+A/399/813/table10Radial velocities and spectral lines for 191 galaxies in A521recnoRecord number assigned by the VizieR team.
