cds-question@unistra.frgalaxiesmillimeter-astronomyphotometrysubmillimeter-astronomyredshiftedinterstellar-mediumWe present 0.2 resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations at 870um in a stellar mass-selected sample of 85 massive (M*>10^11^M_{sun}_) star-forming galaxies (SFGs) at z=1.9-2.6 in the CANDELS/3D-Hubble Space Telescope fields of UDS and GOODS-S. We measure the effective radius of the rest-frame far-infrared (FIR) emission for 62 massive SFGs. They are distributed over wide ranges of FIR size from R_e,FIR_=0.4kpc to R_e,FIR_=6kpc. The effective radius of the FIR emission is smaller by a factor of 2.3_-1.0_^+1.9^ than the effective radius of the optical emission and is smaller by a factor of 1.9_-1.0_^+1.9^ than the half-mass radius. Taking into account potential extended components, the FIR size would change only by ~10%. By combining the spatial distributions of the FIR and optical emission, we investigate how galaxies change the effective radius of the optical emission and the stellar mass within a radius of 1kpc, M_1kpc_. The compact starburst puts most of the massive SFGs on the mass-size relation for quiescent galaxies (QGs) at z~2 within 300Myr if the current star formation activity and its spatial distribution are maintained. We also find that within 300Myr, ~38% of massive SFGs can reach the central mass of M_1kpc_=10^10.5^M_{sun}_, which is around the boundary between massive SFGs and QGs. These results suggest an outside-in transformation scenario in which a dense core is formed at the center of a more extended disk, likely via dissipative in-disk inflows. Synchronized observations at ALMA 870um and James Webb Space Telescope 3-4um will explicitly verify this scenario.2020ApJ...901...74Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/901/74CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/155/271 : Chandra Deep Field-South: Opt. spectroscopy (Szokoly+, 2004)J/ApJ/655/51 : HDFS IRAC observations of 2<z<3.5 galaxies (Wuyts+, 2007)J/ApJ/682/985 : FIREWORKS photometry of GOODS CDF-S (Wuyts+, 2008)J/A+A/511/A50 : JHks of GOODS-South field (Retzlaff+, 2010)J/A+A/532/A90 : PACS Evolutionary Probe (PEP-DR1) catalogs (Lutz+, 2011)J/ApJ/735/86 : NEWFIRM MBS: photometric catalogs (Whitaker+, 2011)J/MNRAS/427/1666 : Massive galaxies in CANDELS-UDS field (Bruce+, 2012)J/ApJS/203/24 : Parameters of galaxies in CANDELS (van der Wel+, 2012)J/A+A/549/A63 : GMASS photometry (Kurk+, 2013)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJS/225/27 : 3D-HST Survey: grism spectra master cat.
