cds-question@unistra.frgalaxiesinfrared-sourcesredshiftedinfrared-photometryThe luminosity-size and mass-size distributions of galaxies out to z~3 are presented. We use very deep near-infrared images of the Hubble Deep Field-South in the J_s_, H, and K_s_ bands, taken as part of FIRES at the VLT, to follow the evolution of the optical rest-frame sizes of galaxies. For a total of 168 galaxies with K_s,AB_ <=23.5, we find that the rest-frame V-band sizes r_e,V_ of luminous galaxies (<L_V_>~2x10^10^h^-2^L_{sun}_) at 2<z<3 are 3 times smaller than for equally luminous galaxies today. In contrast, the mass-size relation has evolved relatively little: the size at mass <M_*_>~2x10^10^h^-2^M_{sun}_ has changed by 20% (+/-20%) since z~2.5. Both results can be reconciled by the fact that the stellar M/L ratio is lower in the luminous high-z galaxies than in nearby ones because they have young stellar populations. The lower incidence of large galaxies at z~3 seems to reflect the rarity of galaxies with high stellar mass.2004ApJ...604..521Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/604/521CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://www.strw.leidenuniv.nl/~fires : FIRES dataJ/A+AS/145/111 : HDF-South catalogue of galaxies (Volonteri+, 2000)J/AJ/122/2205 : HDF-South K photometric redshift catalog (Rudnick+, 2001)J/AJ/125/1107 : Ultra-deep near-IR observation in HDF-S (Labbe+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/604/521https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/604/521http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/604/521https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/604/521https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/604/521http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/604/521GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/604/521/table1Properties of the sample galaxiesrecnoRecord number assigned by the VizieR team.
