cds-question@unistra.frgamma-ray-astronomyactive-galactic-nucleiastronomical-object-identificationIn this paper, we present the Fermi All-sky Variability Analysis (FAVA), a tool to systematically study the variability of the gamma-ray sky measured by the Large Area Telescope on board the Fermi Gamma-ray Space Telescope. For each direction on the sky, FAVA compares the number of gamma-rays observed in a given time window to the number of gamma-rays expected for the average emission detected from that direction. This method is used in weekly time intervals to derive a list of 215 flaring gamma-ray sources. We proceed to discuss the 27 sources found at Galactic latitudes smaller than 10{deg} and show that, despite their low latitudes, most of them are likely of extragalactic origin.2013ApJ...771...57Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/771/57CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012)J/ApJ/756/33 : X-ray sources near 2 {gamma}-ray sources (Cheung+, 2012)J/A+A/548/A106 : PMN J0948+0022 radio-to-gamma-ray monitoring (Foschini+, 2012)J/ApJ/743/171 : The 2LAC catalog (Ackermann+, 2011)J/ApJ/742/66 : New Fermi/LAT extragalactic sources (Teng+, 2011)J/ApJ/741/30 : Radio/{gamma}-ray correlation in AGN (Ackermann+, 2011)J/ApJ/722/520 : Gamma-ray light curves of Fermi blazars (Abdo+, 2010)J/ApJ/722/L7 : Fermi/LAT detected MOJAVE AGNs (Pushkarev+, 2010)J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010)J/A+A/370/468 : Variability of gamma-ray sources (Torres+, 2001)J/ApJS/120/409 : The SMM Atlas of Gamma-Ray flares (Vestrand+, 1999)http://www.asdc.asi.it/feratel/ : List of sources in Fermi LAT ATelshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/771/57https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/771/57http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/771/57https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/771/57https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/771/57http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/771/57GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/771/57/table1 (List of FAVA sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/771/57/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/771/57/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/771/57/table1?GETtext/xml+votable180.050000true4.7665-5.3530.005555555555555556Fermi6/110 437 556 579 863 909 1483 1701 2140 2228 2330 2412 2836 3024 3305 3712 3951 4566 4695 4941 5160 5412 5423 5458 5598 5817 6164 6346 6385 6653 6778 7001 7226 7386 7452 7576 7708 7885 7947 8057 8299 8466 9075 9460 9548 9629 9635 9715 9723 9999 10006 10352 10420 10523 10681 11056 11116 11179 11631 11644 12115 12467 12604 13485 13572 13582 13667 13927 14068 14610 14642 14692 14751 14852 15146 15284 15367 16027 16298 16970 17186 17364 17541 17859 18053 18261 18457 18558 18627 18718 19088 19398 19622 19831 20099 20609 20888 21121 21564 21597 21873 21944 21961 21972 22258 22500 22928 22947 23014 23097 23121 23213 23416 23689 23743 23898 24095 24184 24444 24845 24904 25190 25532 25676 25818 26129 26293 26340 26394 26904 27038 27311 27329 27413 27423 27433 28083 28479 28517 28676 28730 29007 29072 29576 31894 32317 32646 32714 33241 33570 33676 33774 33880 34085 34144 34264 34460 34516 34572 34959 35078 35283 36058 36079 36111 36151 36356 36511 37215 37512 37628 37842 38046 38715 38759 39150 39850 39960 40412 40751 40949 41335 41524 41630 42098 42261 42483 42958 43085 43366 43823 43877 44069 44107 44524 44902 45081 45178 45196 45401 46055 46249 46369 46450 46511 46722 46963 47011 47031 47277 47512 47542 47913 48123 49071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/771/57?format=asciiGamma-raydefaultJ/ApJ/771/57/table1List of FAVA sourcesrecnoRecord number assigned by the VizieR team.
