Accurate stellar mass surface density profiles have been measured for the first time for a complete sample of high-redshift galaxies more massive than 10^10.7^M_{sun}_. The key advantage of this study compared to previous work is that the surface brightness profiles are deconvolved for point-spread function smoothing, allowing accurate measurements of the structure of the galaxies. The surface brightness profiles account for contributions from complex galaxy structures such as rings and faint outer disks. Mass profiles are derived using radial rest-frame ug color profiles and a well-established empirical relation between these colors and the stellar mass-to-light ratio. We derive stellar half-mass radii from the mass profiles, and find that these are on average ~25% smaller than rest-frame g-band half-light radii. This average size difference of 25% is the same at all redshifts, and does not correlate with stellar mass, specific star formation rate, effective surface density, S\'ersic index, or galaxy size. Although on average the difference between half-mass size and half-light size is modest, for approximately 10% of massive galaxies this difference is more than a factor of two. These extreme galaxies are mostly extended, disk-like systems with large central bulges. These results are robust, but could be impacted if the central dust extinction becomes high. ALMA observations can be used to explore this possibility. These results provide added support for galaxy growth scenarios wherein massive galaxies at these epochs grow by accretion onto their outer regions.2013ApJ...763...73Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/763/73CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)II/261 : GOODS initial results (Giavalisco+, 2004)J/ApJS/207/24 : GOODS-S CANDELS multiwavelength catalog (Guo+, 2013)J/ApJ/749/121 : Surface brightness profiles of z=2 galaxies (Szomoru+, 2012)J/ApJ/743/146 : HST/WFC3 observations in HUDF and GOODS-S (Cameron+, 2011)J/ApJ/735/L22 : HUDF galaxy properties at z~2 (Szomoru+, 2011)J/ApJS/183/295 : A K-selected catalog of the ECDFS from MUSYC (Taylor+, 2009)J/ApJ/682/985 : FIREWORKS photometry of GOODS CDF-S (Wuyts+, 2008)J/AJ/132/1729 : Hubble Ultra Deep Field BVI-dropout sources (Beckwith+, 2006)http://sdss.physics.nyu.edu/vagc : Online NYU Value-Added Galaxy Cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/763/73https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/763/73http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/763/73https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/763/73https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/763/73http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/763/73GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/763/73/table1 (Galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/763/73/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/763/73/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/763/73/table1?GETtext/xml+votable180.050000true53.0995583-27.88293610.0055555555555555565/4457 4518 4521 4714 4757 4773 7508 6/0 17406 17751 17761 17764 17767 17776 17805 17811 17812 17814 17822 17825 17827 17832 17833 17836 17837 17840 17842 17858 17998 17999 18008 18011 18013 18014 18019 18022 18026 18028 18063 18066 18067 18069 18076 18078 18082 18090 18091 18092 18685 18686 18687 18766 18771 18775 18781 18788 18789 18790 18802 18831 18838 18843 18845 18849 18851 18854 18855 18860 18861 18864 18865 19005 19023 19026 19032 19035 19036 19037 19041 19044 19047 19051 19056 19086 19096 19097 19098 19100 19101 19106 19108 19110 19114 19121 19122 19200 19201 19202 19456 19457 19458 30036 30041 30044 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/763/73?format=asciiOpticaldefaultJ/ApJ/763/73/table1Galaxy propertiesrecnoRecord number assigned by the VizieR team.
