Fermi-LAT Search for Gamma-ray Emission from AT2018cow
Abstract
We report on a preliminary search for > 100 MeV gamma-ray emission from AT2018cow (ATel #11727) with data from the Fermi Large Area Telescope (LAT). During the 1 week interval from 2018 June 19.5 - 26.0 when the position of the optical transient was within the LAT field of view, we found no significant > 100 MeV gamma-ray emission with a 95% confidence flux upper limit of 100 MeV flux upper limit of Because Fermi normally operates in an all-sky scanning mode, regular gamma-ray monitoring of this source will continue.
