cds-question@unistra.frgalaxiesspectroscopyFossil galaxy groups are speculated to be old and highly evolved systems of galaxies that formed early in the universe and had enough time to deplete their L* galaxies through successive mergers of member galaxies, building up one massive central elliptical, but retaining the group X-ray halo. Considering that fossils are the remnants of mergers in ordinary groups, the merger history of the progenitor group is expected to be imprinted in the fossil central galaxy (FCG). We present for the first time radial gradients of single-stellar population (SSP) ages and metallicities in a sample of FCGs We took deep spectra with the long-slit spectrograph ISIS at the William Herschel Telescope (WHT) for six FCGs.2013A&A...553A..99Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/553/A99CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/553/A99https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/553/A99http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/553/A99https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/553/A99https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/553/A99http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/553/A99GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/553/A99/table1 (Fossil ellipticals observed with ISIS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/553/A99/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/553/A99/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/553/A99/table1?GETtext/xml+votable180.050000true43.215833-1.2746670.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/553/A996/6494 6583 11287 17745 27681 31656https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/553/A99?format=asciidefaultJ/A+A/553/A99/table1Fossil ellipticals observed with ISISNameGalaxy namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
