cds-question@unistra.frgalaxy-clustersgalaxiesphotometryWe have discovered a strong lensing fossil group (J0454) projected near the well-studied cluster MS0451-0305. Using the large amount of available archival data, we compare J0454 to normal groups and clusters. A highly asymmetric image configuration of the strong lens enables us to study the substructure of the system. We used multicolour Subaru/Suprime-Cam and CFHT/Megaprime imaging, together with Keck spectroscopy to identify member galaxies. A VLT/FORS2 spectrum was taken to determine the redshifts of the brightest elliptical and the lensed arc. Using HST/ACS images, we determined the group's weak lensing signal and modelled the strong lens system. This is the first time that a fossil group is analysed with lensing methods. The X-ray luminosity and temperature were derived from XMM-Newton data.2010A&A...514A..60Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/514/A60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/514/A60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/514/A60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/514/A60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/514/A60https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/514/A60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/514/A60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/514/A60/tablea1 (Members of J0454, ordered by increasing separation r from E0454)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/514/A60/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/514/A60/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/514/A60/tablea1?GETtext/xml+votable180.050000true73.5025833-3.14272220.0055555555555555566/229152.191031165672097e-19 2.747921822783228e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/514/A60?format=asciiOpticaldefaultJ/A+A/514/A60/tablea1Members of J0454, ordered by increasing separation r from E0454recnoRecord number assigned by the VizieR team.
