cds-question@unistra.frgalaxy-clustersstellar-massesWe carried out a photometric and structural analysis in the rest-frame V band of a mass-selected (logM/M_{sun}_>10.7) sample of red sequence galaxies in 14 galaxy clusters, six of which are at z>1.45, namely JKCS041, IDCS J1426.5+3508, SpARCS104922.6+564032.5, SpARCSJ022426-032330, XDCPJ0044.0-2033, and SPT-CLJ2040-4451. To this aim, we reduced/analysed about 300 orbits of multicolor images taken with the Advanced Camera for Survey and the Wide Field Camera 3 on Hubble Space Telescope. We uniformly morphologically classified galaxies from z=0.023 to z=1.803, and we homogeneously derived sizes (effective radii) for the entire sample. Furthermore, our size derivation allows, and therefore is not biased by, the presence of the usual variety of morphological structures seen in early-type galaxies, such as bulges, bars, disks, isophote twists, and ellipticity gradients. By such a mass-selected sample, composed of 244 red-sequence early-type galaxies, we find that the log of the galaxy size at a fixed stellar mass, logM/M_{sun}_=11 increases with time with a rate of 0.023+/-0.002dex per Gyr in the last 10Gyr, in marked contrast with the threefold increase found in literature for galaxies in the general field over the same period. This suggests, at face value, to exclude that secular processes are the primary drivers of size evolution, because we observed and environmental environmental dependent size growth. Using spectroscopic ages of Coma early-type galaxies we also find that recently quenched early-type galaxies are a numerically minor population not different in size enough to alter the mean size at a given mass, which implies that the progenitor bias is minor, i.e. that the evolution measured by selecting galaxies at the redshift of observation is indistinguishable from the one that compares ancestors and descendents.2016A&A...593A...2Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/593/A2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/116/429 : Classification of Coma early galaxies (Andreon+ 1996)J/A+AS/126/67 : Coma and Perseus clusters galaxies (Andreon+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/593/A2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/593/A2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/593/A2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/593/A2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/593/A2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/593/A2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/593/A2/table3 (Coordinates, mass and sizes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/593/A2/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/593/A2/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/593/A2/table3?GETtext/xml+votable180.050000true36.67527-4.707380.0055555555555555566/6047 9145 10515 11626 16486 16702 17472 17686 17694 25451 28448 33502 47430https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/593/A2?format=asciidefaultJ/A+A/593/A2/clustersList of studied clustersrecnoRecord number assigned by the VizieR team.
