Fermi-LAT Gravitational Waves Table

This page displays the outcomes of the Fermi-LAT follow-up analysis pipeline that was used to search for electromagnetic counterparts of gravitational waves (GW). For a detailed explanation of the analysis techniques, please refer to 2017ApJ...841L..16V. Furthermore, the Fermi-LAT Collaboration has published additional papers on GW events such as GW150914, LVT151012 and GW151226, GW170104, and GW170817
