Abstract
The discovery of the electromagnetic counterparts to the binary neutron starmerger GW170817 has opened the era of GW+EM multi-messenger astronomy.Exploiting this breakthrough requires increasing samples to explore thediversity of kilonova behaviour and provide more stringent constraints on theHubble constant, and tests of fundamental physics. LSST can play a key role inthis field in the 2020s, when the gravitational wave detector network isexpected to detect higher rates of merger events involving neutron stars($\sim$10s per year) out to distances of several hundred Mpc. Here we proposecomprehensive target-of-opportunity (ToOs) strategies for follow-up ofgravitational-wave sources that will make LSST the premiere machine fordiscovery and early characterization for neutron star mergers and othergravitational-wave sources.
