We seek to explore the internal dynamics of the cluster Abell 545, which has been shown to host a radio halo. Abell 545 is also peculiar for hosting in its center a very bright, red, diffuse intracluster light due to an old, presumably metal-rich stellar population, so bright to be named as "star pile". Our analysis is mainly based on redshift data for 110 galaxies acquired at the Telescopio Nazionale Galileo. We identify 95 cluster members and analyze the cluster internal dynamics by combining galaxy velocities and positions. We also use both multiband photometric data acquired at the Isaac Newton Telescope and X-ray data from the XMM-Newton Science Archive.2011A&A...529A.128Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A128CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/521/A78 : Velocity catalog of A2345 galaxies (Boschin+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A128https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A128http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A128https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A128https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A128http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A128GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/529/A128/table1 (Velocity catalog of 110 spectroscopically measured galaxies in the field of the cluster A545)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A128/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A128/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A128/table1?GETtext/xml+votable180.050000true83.03775-11.51455560.0055555555555555566/213872.381800341673347e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/529/A128?format=asciiOpticaldefaultJ/A+A/529/A128/table1Velocity catalog of 110 spectroscopically measured galaxies in the field of the cluster A545recnoRecord number assigned by the VizieR team.
