cds-question@unistra.frsurveysWe have combined spectroscopic and photometric data from the Sloan Digital Sky Survey with 1.4GHz radio observations, conducted as part of the Stripe 82 1-2GHz Snapshot Survey using the Karl G. Jansky Very Large Array, which covers ~100 sq deg, to a flux limit of 88uJy rms. Cross-matching the 11768 radio source components with optical data via visual inspection results in a final sample of 4794 cross-matched objects, of which 1996 have spectroscopic redshifts and 2798 objects have photometric redshifts. Three previously undiscovered giant radio galaxies were found during the cross-matching process, which would have been missed using automated techniques. For the objects with spectroscopy, we separate radio-loud active galactic nuclei (AGN) and star-forming galaxies (SFGs) using three diagnostics and then further divide our radio-loud AGN into the high and low excitation radio galaxy (HERG and LERG) populations. A control-matched sample of HERGs and LERGs, matched on stellar mass, redshift, and radio luminosity, reveals that the host galaxies of LERGs are redder and more concentrated than HERGs. By combining with near-infrared data, we demonstrate that LERGs also follow a tight K-z relationship. These results imply the LERG populations are hosted by population of massive, passively evolving early-type galaxies. We go on to show that HERGs, LERGs, quasars, and SFGs in our sample all reside in different regions of a Wide-field Infrared Survey Explorer colour-colour diagram. This cross-matched sample bridges the gap between previous 'wide but shallow' and 'deep but narrow' samples and will be useful for a number of future investigations.2018MNRAS.480..707Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/480/707CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/460/4433 : SDSS Stripe 82 VLA 1-2GHz survey (Heywood+, 2016)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/480/707https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/480/707http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/480/707https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/480/707https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/480/707http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/480/707GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/480/707/s82cat (S82 cross-matched catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/480/707/s82cat?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/480/707/s82cat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/480/707/s82cat?GETtext/xml+votable180.050000true9.89870.27240.0055555555555555565/4453-4454 4457-4458 4460 4464 4501-4503 4505-4506 4508 4709-4710 4713-4714 4757-4758 4761 6/17661-17663 17723 17725-17727 17768 17770-17771 17805-17807 17809-17811 17820-17822 17825-17827 17836-17838 17848 17981-17983 17997-17999 18001-18003 18017-18019 18028-18030 18040 18068-18069 18071 18112-18114 18176-18178 18685-18687 18749-18751 18792 18794-18795 18823 18829-18831 18833-18835 18844-18846 18849-18851 18860-18862 18864-18866 18880-18882 19015 19019 19021-19023 19025-19027 19036-19038 19041 19053 19056-19058 19200-19202https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/480/707?format=asciiOpticaldefaultJ/MNRAS/480/707/s82catS82 cross-matched catalogueSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
