Issue Date: | 2019 | Journal: | THE ASTROPHYSICAL JOURNAL | Number: | 870 | Issue: | 2 | First Page: | 136 | Abstract: | The origin of cosmic neutrinos is still largely unknown. Using data obtained by the gamma-ray imager on board the Astro-rivelatore Gamma a Immagini Leggero (AGILE) satellite, we systematically searched for transient gamma-ray sources above 100 MeV that are temporally and spatially coincident with 10 recent high-energy neutrino IceCube events. We found three AGILE candidate sources that can be considered possible counterparts to neutrino events. Detecting three gamma-ray/neutrino associations out of 10 IceCube events is shown to be unlikely due to a chance coincidence. One of the sources is related to the BL Lac source TXS 0506+056. For the other two AGILE gamma-ray sources there are no obvious known counterparts, and both Galactic and extragalactic origin should be considered. | URI: | http://hdl.handle.net/20.500.12386/29513 | URL: | https://iopscience.iop.org/article/10.3847/1538-4357/aaf1c0 | ISSN: | 0004-637X | DOI: | 10.3847/1538-4357/aaf1c0 | Bibcode ADS: | 2019ApJ...870..136L | Fulltext: | open |
