cds-question@unistra.frgalaxy-clustersredshiftedUsing a sample of 98 galaxy clusters recently imaged in the near-infrared with the European Southern Observatory (ESO) New Technology Telescope, WIYN telescope and William Herschel Telescope, supplemented with 33 clusters from the ESO archive, we measure how the stellar mass of the most massive galaxies in the universe, namely brightest cluster galaxies (BCGs), increases with time. Most of the BCGs in this new sample lie in the redshift range 0.2<z<0.6, which has been noted in recent works to mark an epoch over which the growth in the stellar mass of BCGs stalls. From this sample of 132 clusters, we create a subsample of 102 systems that includes only those clusters that have estimates of the cluster mass. We combine the BCGs in this subsample with BCGs from the literature, and find that the growth in stellar mass of BCGs from 10 billion years ago to the present epoch is broadly consistent with recent semi-analytic and semi-empirical models. As in other recent studies, tentative evidence indicates that the stellar mass growth rate of BCGs may be slowing in the past 3.5 billion years. Further work in collecting larger samples, and in better comparing observations with theory using mock images, is required if a more detailed comparison between the models and the data is to be made.2016MNRAS.460.2862Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/460/2862CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/460/2862https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/460/2862http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/460/2862https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/460/2862https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/460/2862http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/460/2862GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/460/2862/table2 (Observational summary)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/2862/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/2862/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/2862/table2?GETtext/xml+votable180.050000true0.2501667-57.805750.005555555555555556Cone search capability for table J/MNRAS/460/2862/table5 (BCG results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/2862/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/2862/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/2862/table5?GETtext/xml+votable180.050000true0.25025-57.80928610.0055555555555555566/3 687 2230 4130 4206 4406 4512 4605 5100 5701 6432 9588 10141 10607 11080 12290 12642 16486 16787 17171 17222 17224 17247 17487 17506 17741 17746 17749-17750 17768-17769 17771-17772 17805 17809 17840 17856 17860 18005 18012 18021 18028 18081 18084 18087 18093 18122 18475 18534 18627 18774 18800 18827 18831 18841 18864 18894 18943 18957 19009 19027 19029 19036 19042 19097 19102 19124 19370 19416 19542 19858 20128 20536 20735 21766 22577 22607 22661 22915 22970 22972 23144 23147 23192 23195 25451 25675 25981 26037 26128 26177 26189 26707 26787 26983 27075 27476 27742 28220 30033 30045 30060 32500 33622 33649 33711 33713 33718 33725 33741 33783 33878 33894 33945 34035 34049 34059 34674 34726 34793 34910 34954 35388 36082 36423 36861 37395 39010 39043 39068 39102 39428 39586 45006 45543 46474 46571 48076 484237.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/460/2862?format=asciidefaultJ/MNRAS/460/2862/table2Observational summarySimbadNameSimbad column added by the CDSmeta.idcharr_zReference for redshift (G1)meta.ref;pos.framecharrecnoRecord number assigned by the VizieR team.
