cds-question@unistra.frgalaxy-clustersredshiftedradio-sourcesx-ray-sourcesapparent-magnitudeWe present results from optical, X-ray and radio observations of two X-ray bright (L_X_~10^45^erg/s) galaxy clusters. Abell 1451 is at redshift z=0.1989 and has line-of-sight velocity dispersion {sigma}_V_=1330km/s as measured from 57 cluster galaxies. It has regular X-ray emission without signs of substructure, a Gaussian velocity distribution, lack of a cooling flow region and significant deviations from the observed scaling laws between luminosity, temperature and velocity dispersion, indicating a possible merging shock. There is only one spectroscopically confirmed cluster radio galaxy, which is close to the X-ray peak. 1RXS J131423.6-251521 (for short RXJ1314-25) has z=0.2474 and {sigma}_V_=1100km/s from 37 galaxies. There are two distinct galaxy groups with a projected separation of ~700kpc. The velocity histogram is bi-modal with a redshift-space separation of ~1700km/s, and the X-ray emission is double peaked. Although there are no spectroscopically confirmed cluster radio galaxies, we have identified a plausible relic source candidate.2002A&A...392..795Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/392/795CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/392/795https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/392/795http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/392/795https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/392/795https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/392/795http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/392/795GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/392/795/table3 (A1451 spectroscopic catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/795/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/795/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/795/table3?GETtext/xml+votable180.050000true180.7475-21.5613890.005555555555555556Cone search capability for table J/A+A/392/795/table4 (1RXS J131423.6-25152 spectroscopic catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/795/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/795/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/795/table4?GETtext/xml+votable180.050000true198.56125-25.2197220.005555555555555556Cone search capability for table J/A+A/392/795/table11 (Radio sources for Abell 1451 and 1RXS J131423.6-25152 within 1 Abell radius of the cluster centre)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/795/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/795/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/795/table11?GETtext/xml+votable180.050000true180.7152917-21.44327780.005555555555555556Cone search capability for table J/A+A/392/795/table12 (Radio-optical identifications in Abell 1451 and 1RXS J131423.6-25152)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/795/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/795/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/795/table12?GETtext/xml+votable180.050000true180.7148333-21.44316670.0055555555555555566/24822-24823 44008https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/392/795?format=asciiX-rayOpticalRadiodefaultJ/A+A/392/795/table3A1451 spectroscopic cataloguerecnoRecord number assigned by the VizieR team.
