cds-question@unistra.frgalaxiesinfrared-sourceshst-photometrygalaxy-classification-systemsWe use deep Hubble Space Telescope Wide Field Camera 3 near-infrared imaging obtained of the GOODS-South field as part of the CANDELS survey to investigate a stellar mass-limited sample of quiescent galaxies at 1.5<z<2.5. We measure surface brightness profiles for these galaxies using a method that properly measures low surface brightness flux at large radii. We find that quiescent galaxies at z~2 very closely follow Sersic profiles, with n_median_=3.7, and have no excess flux at large radii. Their effective radii are a factor of ~4 smaller than those of low-redshift quiescent galaxies of similar mass. However, there is a significant spread in sizes ({sigma}_log_10_r_e__=0.24), with the largest z~2 galaxies lying close to the z=0 mass-size relation. We compare the stellar mass surface density profiles with those of massive elliptical galaxies in the Virgo Cluster and confirm that most of the mass growth which occurs between z~2 and z=0 must be due to accretion of material onto the outer regions of the galaxies. Additionally, we investigate the evolution in the size distribution of massive quiescent galaxies. We find that the minimum size growth required for z~2 quiescent galaxies to fall within the z=0 size distribution is a factor of ~2 smaller than the total median size growth between z~2 and z=0.2012ApJ...749..121Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/749/121CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)J/ApJS/206/10 : CANDELS multiwavelength catalog (Galametz+, 2013)J/MNRAS/427/1666 : Massive galaxies in CANDELS-UDS field (Bruce+, 2012)J/ApJS/203/24 : Structural parameters of CANDELS galaxies (van der Wel+, 2012)J/ApJ/742/111 : Extreme emission-line galaxies in CANDELS (van der Wel+, 2011)J/MNRAS/400/1690 : Ages and metallicities for quiescent galaxies (Smith+, 2009)J/ApJ/682/985 : FIREWORKS photometry of GOODS CDF-S (Wuyts+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/749/121https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/749/121http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/749/121https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/749/121https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/749/121http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/749/121GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/749/121/table1 (Galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/749/121/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/749/121/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/749/121/table1?GETtext/xml+votable180.050000true53.06982889-27.880466940.0055555555555555566/35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/749/121?format=asciiOpticalInfrareddefaultJ/ApJ/749/121/table1Galaxy propertiesrecnoRecord number assigned by the VizieR team.
