Abstract

The discovery of the GW signal from the merging of two neutron stars (GW170817) and the detection of related electromagnetic radiations, namely a short GRB, an optical transient (kilonova) and a late afterglow emission at X-ray and radio wavelengths, opened the new era of multi-messenger astrophysics. I will briefly review the history of this discovery with an emphasis on the results of the optical/near-infrared follow-up. The lesson learned is used to get prepared for the forthcoming LIGO/Virgo runs.
