cds-question@unistra.frgalaxiesspectroscopyredshiftedsurveysWe present an analysis of the size growth seen in early-type galaxies over 10Gyr of cosmic time. Our analysis is based on a homogeneous synthesis of published data from 16 spectroscopic surveys observed at similar spatial resolution, augmented by new measurements for galaxies in the Gemini Deep Deep Survey. In total, our sample contains structural data for 465 galaxies (mainly early-type) in the redshift range 0.2<z<2.7. The size evolution of passively evolving galaxies over this redshift range is gradual and continuous, with no evidence for an end or change to the process around z~1, as has been hinted at by some surveys which analyze subsets of the data in isolation. The size growth appears to be independent of stellar mass, with the mass-normalized half-light radius scaling with redshift as R_e_{propto}(1+z)^-1.62+/-0.34^. Surprisingly, this power law seems to be in good agreement with the recently reported continuous size evolution of UV-bright galaxies in the redshift range z~0.5-3.5. It is also in accordance with the predictions from recent theoretical models.2011ApJ...739L..44Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/739/L44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/261 : GOODS initial results (Giavalisco+, 2004)II/258 : Hubble Ultra Deep Field Catalog (UDF) (STScI, 2004)J/A+A/549/A63 : GMASS photometry (Kurk+, 2013)J/A+A/524/A6 : Evolution of spectral early-type galaxies (Saglia+, 2010)J/ApJS/183/295 : A K-selected catalog of the ECDFS from MUSYC (Taylor+, 2009)J/AJ/134/1103 : MUSYC deep near-infrared imaging (Quadri+, 2007)J/MNRAS/382/109 : Massive galaxies in Extended Groth Strip (Trujillo+, 2007)J/ApJS/162/1 : MUSYC: optical source catalog (Gawiser+, 2006)J/ApJ/633/174 : Spheroidals and bulge dominated galaxies (Treu+, 2005)J/ApJ/635/243 : Sample of GOODS/CDFS early-type galaxies (Ferreras+, 2005)J/AJ/127/2455 : Gemini Deep Deep Survey (GDDS) (Abraham+, 2004)J/ApJ/464/79 : CFRS XI: High-redshift galaxies morphology (Schade+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/739/L44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/739/L44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/739/L44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/739/L44https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/739/L44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/739/L44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/739/L44/table2 (Complete list of objects used to construct the size evolution diagram)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/739/L44/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/739/L44/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/739/L44/table2?GETtext/xml+votable180.050000true160.16791694-11.93450.0055555555555555566/2441 4567 5345 9343 11252 11424 11425 17703 19033 19036 23208 23209 23210 25071 25327 25416 25418 25419 25484 25540 25667 26222 26614 26654 26676 26677 26689 26691 26694 27009 27440 28538 31386 31730 35935 43945 43947 45526https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/739/L44?format=asciiOpticaldefaultJ/ApJ/739/L44/table2Complete list of objects used to construct the size evolution diagramNEDnameSimbad column added by the CDSmeta.idcharn[0.5/9]?
