cds-question@unistra.frradio-sourcesinfrared-sourcesWe made two new sensitive (rms noise {sigma}_n_~1{mu}Jy/beam) high-resolution ({theta}=3.0" and {theta}=0.66" FWHM) S-band (2<{nu}<4GHz) images covering a single JVLA primary beam (FWHM~14') centered on RAJ2000=10:46,DEJ2000=+59:01 in the Lockman Hole. These images yielded a catalog of 792 radio sources, 97.7+/-0.8% of which have infrared counterparts stronger than S~2{mu}Jy at {lambda}=4.5{mu}m. About 91% of the radio sources found in our previously published, comparably sensitive low-resolution ({theta}=8" FWHM) image covering the same area were also detected at 0.66" resolution, so most radio sources with S(3GHz)>~5{mu}Jy have angular structure {phi}<~0.66". The ratios of peak brightness in the 0.66" and 3" images have a distribution indicating that most {mu}Jy radio sources are quite compact, with a median Gaussian angular diameter <{phi}>=0.3"+/-0.1" FWHM and an rms scatter {sigma}_{phi}_<~0.3" of individual sizes. Most of our {mu}Jy radio sources obey the tight far-infrared/radio correlation, indicating that they are powered by star formation. The median effective angular radius enclosing half the light emitted by an exponential disk is <{rho}_e_>~<{phi}>/2.43~0.12", so the median effective radius of star-forming galaxies at redshifts z~1 is <r_e_>~1.0kpc.2018ApJ...856...67Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/856/67CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/95 : Herschel Multi-tiered Extragalactic Survey (Oliver+, 2012)J/A+A/398/901 : VLA survey at 6 cm in the Lockman Hole (Ciliegi+, 2003)J/MNRAS/371/963 : Deep VLA survey in Lockman Hole, HDFN, ELAIS (Biggs+, 2006)J/AJ/136/1889 : 20cm observations of deep Swire Field (Owen+, 2008)J/MNRAS/387/1037 : 610-MHz survey of Lockman Hole with GMRT (Garn+, 2008)J/ApJ/714/1305 : The Deep SWIRE Field (DSF) IV.
