cds-question@unistra.fractive-galactic-nucleigamma-ray-astronomypulsarsbl-lacertae-objectssurveysWe present the second AGILE-GRID catalogue (2AGL) of gamma-ray sources in the energy range 100MeV-10GeV. With respect to previous AGILE-GRID catalogues, the current 2AGL catalogue is based on the first 2.3 years of science data from the AGILE mission (the so-called pointing mode) and incorporates more data and several analysis improvements, including better calibrations at the event reconstruction level, an updated model for the Galactic diffuse gamma-ray emission, a refined procedure for point-like source detection, and the inclusion of a search for extended gamma-ray sources. The 2AGL catalogue includes 175 high-confidence sources (above 4{sigma} significance) with their location regions and spectral properties and a variability analysis with four-day light curves for the most significant. Relying on the error region of each source position, including systematic uncertainties, 122 sources are considered as positionally associated with known counterparts at different wavelengths or detected by other gamma-ray instruments. Among the identified or associated sources, 62 are active galactic nuclei (AGNs) of the blazar class. Pulsars represent the largest Galactic source class, with 41 associated pulsars, 7 of which have detected pulsation; 8 supernova remnants and 4 high-mass X-ray binaries have also been identified. A substantial number of 2AGL sources are unidentified: for 53 sources no known counterpart is found at different wavelengths. Among these sources, we discuss a subclass of 29 AGILE-GRID-only gamma-ray sources that are not present in 1FGL, 2FGL, or 3FGL catalogues; the remaining sources are unidentified in both 2AGL and 3FGL catalogues. We also present an extension of the analysis of 2AGL sources detected in the energy range 50-100MeV.2019A&A...627A..13Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/627/A13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/506/1563 : First AGILE catalog of gamma-ray sources (Pittori+, 2009)J/A+A/558/A137 : AGILE bright gamma-ray sources updated list (Verrecchia+ 2013)J/A+A/587/A93 : MeV-GeV counterparts of TeV sources (Rappoldi+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/627/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/627/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/627/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/627/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/627/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/627/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/627/A13/table10 (2AGL Catalogue sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/627/A13/table10?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/627/A13/table10?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/627/A13/table10?GETtext/xml+votable180.050000true1.7773.130.0055555555555555566/579 1701 2411 2838 3128 3302 3308 3651 3819 3891 5423 6015 6327 6507 6777 7896 8299 9721 10341 10971 12117 12604 12619 13095 13748 13927 14270 14424 14460 14608 14619 14644 14692 14696 14712 14751 14840 15310 15406 15644 15676 15971 16027 16170 16223 16253 17857 18156 18574 18626 19370 19395 20099 20104 20127 20481 21121 21564 22255 22947 23952 23995 24084 24185 24774 25203 26131 26292 28673 28805 28812 28814 28824-28826 28828 28830 28849 28855 28875 28892 28899 28912 28918 29018 29072 29119 29160 29162 29174 29182 29255 29471 29504-29505 29513 29884 30219 30244 30262 30299 30316 30319 30330 30422 30443 30593 30601 30616 30692 30996 31002 34123 34572 36279 36940 36956 37042 37214 37244 37341-37342 37361 37365 37912 37921 37923 38016-38017 38022 38081 39235 41007 41046 41074 41335 41681 41684 41743 41756 41758 42043 42173 42186 42188 42204 42215 42226 42234 42384 42436 42444 42484 42520 42901 42970 42980 42983 43005 43040 43085 43262 43905 44069 44372 44908 45232 46066 47011 47359 48123 49071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/627/A13?format=asciiGamma-rayRadiodefaultJ/A+A/627/A13/table102AGL Catalogue sources2AGL2AGL Source Name (G1)meta.id;meta.maincharRadRadius (2)degphys.angSizefloatrecnoRecord number assigned by the VizieR team.
