cds-question@unistra.frbl-lacertae-objectsactive-galactic-nucleiredshiftedradio-sourcesgamma-ray-astronomySupplementing existing survey data with Very Large Array (VLA) observations, we have extended {gamma}-ray counterpart identifications down to decl.=-40{deg} using our "figure-of-merit" approach. We find blazar counterparts for 70% of EGRET sources above decl.=-40{deg} away from the Galaxy. Spectroscopic confirmation is in progress, and spectra for 24 sources are presented here. We find evidence that increased exposure in the bulge region allowed EGRET to detect relatively faint blazars; a clear excess of nonblazar objects in this region, however, argues for an additional (new) source class.2004ApJ...609..564Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/609/564CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/123/79 : Third EGRET catalog (3EG) (Hartman+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/609/564https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/609/564http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/609/564https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/609/564https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/609/564http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/609/564GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/609/564/table1 (3EG Objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/609/564/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/609/564/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/609/564/table1?GETtext/xml+votable180.050000true9.74-9.820.005555555555555556Cone search capability for table J/ApJ/609/564/table2 (VLA A-Array 8.4GHz Observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/609/564/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/609/564/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/609/564/table2?GETtext/xml+votable180.050000true9.7762125-9.713022220.0055555555555555566/17236 17411 17414 17417 17734 18496 18718 18737 18743 18784 20509 20552 20647 20649 21035 21318 21321 21324 21368 21431 21769 22917 22947 23099 23121 25020 25021 25022 25069 25071 25214 25625 25626 25630 25649 25834 25835 25864 26115 26118 26119 26131 26176 26244 26245 28673 28675 28767 28809 28825 28830 28848 28894 28912 28932 28934 28935 29002 29008 29009 29016 29018 29072 29074 29117 29190 29249 29261 29309 29311 29324 29374 29469 29505 29539 29570 29593 29615 29626 29641 29675 29686 29692 29703 29714 29833 29836 30112 30115 30241 30247 30724 30746 30757 30781 30783 30807 30829 30840 30843 30860 30869 30917 31001 31002 31044 31113 31116 31255 31262 34260 34263 35304 36186 36187 36188 36197 36837 36839 39542 39543 39545 39746 39752 39962 40762 40766 40848 42356 42435 42481 42486 42807 42901 42935 42949 42980 42981 43359 43380 43819 43822 44058 44059 44069 44155 44241 44244 44247 44329 44331 44334 44356 44357 44629 44802 44805 44807 44813 44815 44818 44908 47014 47862 47893 47895 47938 48123 48268 48270 48292 48685 48845 48874 49071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/609/564?format=asciiGamma-rayOpticalRadiodefaultJ/ApJ/609/564/table13EG ObjectsrecnoRecord number assigned by the VizieR team.
