cds-question@unistra.frgalaxiesinfrared-sourcesgamma-ray-astronomygamma-ray-burstsWe identify and explore the properties of an infrared-bright gamma-ray burst (GRB) host population. Candidate hosts are selected by coincidence with sources in WISE, with matching to random coordinates and a false alarm probability analysis showing that the contamination fraction is ~0.5. This methodology has already identified the host galaxy of GRB 080517. We combine survey photometry from Pan-STARRS, SDSS, APASS, 2MASS, GALEX, and WISE with our own WHT/ACAM and VLT/X-shooter observations to classify the candidates and identify interlopers. Galaxy SED fitting is performed using MAGPHYS, in addition to stellar template fitting, yielding 13 possible IR-bright hosts. A further seven candidates are identified from the previously published work. We report a candidate host for GRB 061002, previously unidentified as such. The remainder of the galaxies have already been noted as potential hosts. Comparing the IR-bright population properties including redshift z, stellar mass M*, star formation rate SFR, and V-band attenuation A_V_ to GRB host catalogues in the literature, we find that the infrared-bright population is biased towards low z, high M*, and high A_V_. This naturally arises from their initial selection - local and dusty galaxies are more likely to have the required IR flux to be detected in WISE. We conclude that while IR-bright GRB hosts are not a physically distinct class, they are useful for constraining existing GRB host populations, particularly for long GRBs.2018MNRAS.478....2Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/478/2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/478/2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/478/2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/478/2https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/478/2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/478/2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/478/2/table1 (The 55 GRB X-ray positions for which a catalogued WISE source is identified within 1.5R90 of the X-ray error circle centroid, and is not rejected based on FAP, CCF, or blend cuts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/2/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/2/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/2/table1?GETtext/xml+votable180.050000true166.4124-40.68420.005555555555555556Cone search capability for table J/MNRAS/478/2/table2 (The 15 GRB X-ray positions which match to at least one WISE source within 1.5R90, but which have these matches rejected due to FAP, CCF, or WISE blending cuts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/2/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/2/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/2/table2?GETtext/xml+votable180.050000true358.470865.93890.0055555555555555566/210 590 1941 2574 4108 5080 7044 7430 7519 8182 8761 9860 10278 10704 11140 11307 11649 11905 13005 13558 14335 14913 15246 19530 20191 21595 24018 25426 26441 27008 28234 28442 28786 28863 29240 29394 29867 30303 31185 31241 31408 33061 33735 33912 33925 34364 34440 36361 36468 36528 37351 38301 39008 39043 39691 40559 41442 41586 42175 42361 42840 42865 42952 43015 44419 45510 45762 46789 47253 483197.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/478/2?format=asciiGamma-rayInfrareddefaultJ/MNRAS/478/2/table1The 55 GRB X-ray positions for which a catalogued WISE source is identified within 1.5R90 of the X-ray error circle centroid, and is not rejected based on FAP, CCF, or blend cutsrecnoRecord number assigned by the VizieR team.
