cds-question@unistra.frgalaxiesinfrared-sourcesgalaxy-radiiastrometryradial-velocityKnowledge about the large-scale distribution of galaxies is far from complete in the Zone of Avoidance (ZoA), which is mostly due to high interstellar extinction and to source confusion at lower Galactic latitudes. Past near-infrared (NIR) surveys, such as the Two Micron All Sky Survey (2MASS), have shown the power of probing large-scale structure at these latitudes. Our aim is to map the galaxy distribution across the Southern Galactic plane using the VISTA Variables in the Via Lactea Survey (VVV), which reach 2-4mag deeper than 2MASS. We used SEXTRACTOR+PSFEX to identify extended objects and to measure their sizes, the light concentration index, magnitudes, and colours. Morphological and colour constraints and visual inspection were used to confirm galaxies. We present the resulting VVV NIR Galaxy Catalogue (VVV NIRGC) of 5563 visually confirmed galaxies, of which only 45 were previously known. This is the largest catalogue of galaxies towards the Galactic plane, with 99 per cent of these galaxies being new discoveries. We found that the galaxy density distribution closely resembled the distribution of low interstellar extinction of the existing NIR maps. We also present a description of the 185 2MASS extended sources observed in the region, of which 16 per cent of these objects had no previous description, which we have now classified. We conclude that interstellar extinction and stellar density are the main limitations for the detection of background galaxies in the ZoA. The VVV NIRGC is a new data set providing information for extragalactic studies in the Galactic plane.2021MNRAS.502..601Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/502/601CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/466/481 : Near-infrared survey around PKS 1343-601 (Schroeder+, 2007)J/MNRAS/443/41 : Deep NIR photometry of HI galaxies in ZoA (Williams+, 2014)J/MNRAS/462/3386 : Deep NIR catalogue of HIZOA galaxies (Said+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/502/601https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/502/601http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/502/601https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/502/601https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/502/601http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/502/601GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/502/601/vvvnirgc (VVV near-IR galaxy catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/601/vvvnirgc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/601/vvvnirgc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/601/vvvnirgc?GETtext/xml+votable180.050000true173.9517917-63.90952780.005555555555555556Cone search capability for table J/MNRAS/502/601/tablea1 (VVV tiles in the Galactic disc)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/601/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/601/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/601/tablea1?GETtext/xml+votable180.050000true175.8537-63.5273280.005555555555555556Cone search capability for table J/MNRAS/502/601/tableb1 (2MASX extragalactic sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/601/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/601/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/601/tableb1?GETtext/xml+votable180.050000true177.453238-64.0018620.005555555555555556Cone search capability for table J/MNRAS/502/601/tableb2 (2MASX Galactic sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/502/601/tableb2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/502/601/tableb2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/502/601/tableb2?GETtext/xml+votable180.050000true175.122987-63.4644830.0055555555555555564/2603 2610 2613 5/9473 9476-9477 10398 10417-10422 10424-10425 10438-10439 10444-10446 10449-10450 10456 10464 10539 10541-10542 10554-10555 10596-10597 10599-10600 10608-10610 10624-10625 10628 10753-10756 10760 10762 6/37891 37897 37900 37952 41466-41467 41469-41471 41582-41583 41590-41591 41596-41598 41629-41631 41645-41647 41665-41667 41692-41694 41704-41706 41708 41712 41742-41743 41750-41751 41788-41790 41793-41795 41805-41807 41828-41830 41832 41840-41841 41860-41861 42150-42151 42153-42155 42162-42163 42172 42174-42175 42187 42190-42191 42201-42202 42204-42206 42208-42210 42212-42214 42224 42226-42228 42230-42234 42236-42237 42303 42346-42347 42350-42351 42362 42370-42371 42373-42378 42380 42382-42383 42392 42394-42395 42404-42406 42416-42417 42420-42421 42444 42446-42448 42464-42465 42468-42469 42504-42505 42508 42516-42517 42560 43009-43011 43028-43030 43032-43034 43044-43046 43136https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/502/601?format=asciiInfrareddefaultJ/MNRAS/502/601/vvvnirgcVVV near-IR galaxy cataloguerecnoRecord number assigned by the VizieR team.
