Multi-messenger astronomy with the γ-ray satellite AGILE: gravitational wave events and ultra-high energy astrophysical neutrinos

Abstract We report the results of an extensive search through the AGILE data for γ-ray counterparts to the LIGO gravitational-wave (GW) events detected in the O1 run corresponding to the period from September 12 2015 to January 19, 2016 and in the O2 run corresponding to the period from November 30, 2016 to August 25, 2017. We report as well the results of a search through the AGILE data for γ-ray counterparts to the IceCube neutrino events. Currently in spinning mode, AGILE has the potential of covering about 80% of the whole sky with its γ-ray instrument, with more than 100 useful passes every day for any accessible sky region and is ready to be operative during the incoming LIGO/VIRGO O3 run.
