cds-question@unistra.frgalaxy-clustersgalaxiesphotometryradial-velocityThe mechanisms giving rise to diffuse radio emission in galaxy clusters, and in particular their connection with cluster mergers, are still debated. We seek to explore the internal dynamics of the cluster Abell 2294, which has been shown to host a radio halo. Our analysis is mainly based on redshift data for 88 galaxies acquired at the Telescopio Nazionale Galileo. We combine galaxy velocities and positions to select 78 cluster galaxies and analyze its internal dynamics. We also use both photometric data acquired at the Isaac Newton Telescope and X-ray data from the Chandra archive.2010A&A...517A..65Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/517/A65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/517/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/517/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/517/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/517/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/517/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/517/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/517/A65/table1 (Velocity catalog of 88 spectroscopically measured galaxies in the field of the cluster A2294)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/517/A65/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/517/A65/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/517/A65/table1?GETtext/xml+votable180.050000true260.257291785.85586110.0055555555555555566/12253 12255https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/517/A65?format=asciidefaultJ/A+A/517/A65/table1Velocity catalog of 88 spectroscopically measured galaxies in the field of the cluster A2294Seq[1/88] Sequential number, <[GBB2010b] NN> in Simbadmeta.id;meta.mainintprimaryn_Seq[*i] * for BCG, i for non-member galaxiesmeta.code.membercharRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainBmagINT Harris B magnitudemagphot.mag;em.opt.BfloatRmagINT Harris R magnitudemagphot.mag;em.opt.RfloatHRVHeliocentric radial velocitykm/sspect.dopplerVeloc;pos.heliocentricinte_HRVrms uncertainty on HRVkm/sstat.errorintEmEmission linesmeta.noteSimbadSimbad column added by the CDSmeta.ref.urlchar
