cds-question@unistra.frgalaxiesphotometrygamma-ray-astronomyinfrared-photometryResults of a deep, near-infrared survey of a predetermined, consistent sample of gamma-ray burst localizations are presented. This systematic study, conducted from 1994 to 1996, is the first to be designed specifically to examine the extragalactic content of these regions of sky. JHK images of nine of the smallest error boxes from the third Interplanetary Network together with 70arcmin^2^ of control fields were obtained reaching levels up to 200 times fainter than those reached by previous infrared studies of burst locations. Photometric measurements and star/galaxy separation measurements of more than 3000 detected objects were made. An overabundance of brighter galaxies exists in the gamma-ray burst images at the 98% confidence level, which indicates that the bursts are cosmological. Both the level of this enhancement and the galaxy brightness, where it appears, match what is expected for host galaxies. As a group, the brightest galaxy within each error box is slightly brighter than normal but is still consistent with a random population of galaxies. Their positions within the boxes are also consistent with a random distribution, with no preference toward the center. The bright galaxy excess in these regions of sky, combined with a seemingly random population of brightest error box galaxies, suggest that either the true host galaxies are fainter or the error boxes do not point accurately to the hosts.1997ApJ...491...93Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/491/93CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/20 : The Fourth BATSE Burst Catalog (Paciesas+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/491/93https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/491/93http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/491/93https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/491/93https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/491/93http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/491/93GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/491/93/grbcat (Catalogue of sources in 9 {gamma}-ray burst fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/491/93/grbcat?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/491/93/grbcat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/491/93/grbcat?GETtext/xml+votable180.050000true296.9134-70.67560.0055555555555555566/10482 11793 14470 16101 16103 19986 39414 39420 45597 47177 47507https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/491/93?format=asciiGamma-rayOpticalInfrareddefaultJ/ApJ/491/93/grbcatCatalogue of sources in 9 {gamma}-ray burst fieldsrecnoRecord number assigned by the VizieR team.
