Specifically, we sought evidence from the optical data for the putative cluster merger believed to be responsible for the observed radio and X-ray emission. We present 184 new redshifts in the region, of which 143 correspond to member galaxies of A3667. We find the cluster velocity distribution to be well modelled by a single Gaussian in agreement with previous results. In addition, new redshift-selected isodensity plots significantly reduce the prominence of the previously reported subgroup to the north-west of the main cluster. Instead, we find the galaxy distribution to be elongated and well mixed, with a high velocity dispersion and no significant evidence for substructure. These results are consistent with the axis of the proposed merger being close to the plane of the sky.2008A&A...479....1Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/479/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/259/233 : Cluster SC2008-57(A3667) (Sodre+ 1992)VII/250 : The 2dF Galaxy Redshift Survey (2dFGRS) (2dFGRS Team, 1998-2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/479/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/479/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/479/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/479/1https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/479/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/479/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/479/1/table2 (Spectroscopic parameters for 143 galaxies in A3667)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/479/1/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/479/1/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/479/1/table2?GETtext/xml+votable180.050000true301.4062083-56.68502780.0055555555555555566/45813 45815 45962-45963 45984-45986https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/479/1?format=asciiOpticaldefaultJ/A+A/479/1/table2Spectroscopic parameters for 143 galaxies in A3667IDSource identification number used in papermeta.id;instr.setupintrecnoRecord number assigned by the VizieR team.
