Abstract: The achieved advances in gravitational wave (GW) detectors and the strong coordinations among different observatories are paving the way for a “golden era” of multi-messenger astronomy. Among the GW sources that we can detect with ground-based interferometers, there are compact binary coalescences as well as core-collapsing massive stars and isolated neutron stars. We expect to observe several electromagnetic (EM) counterparts associated with these sources, such as gamma-ray bursts and their afterglows, kilonovae, millisecond pulsars, soft gamma repeaters and core-collapse supernovae. Joint GW and EM observations enable us to gain much deeper insights on the nature of these astrophysical sources compared to observing them only through GWs or EM radiation, and allow us to tackle several aspects of fundamental physics and cosmology. In this talk I will describe the current status of the observations of GW sources and their electromagnetic counterparts and the future perspectives for joint multi-messenger observational campaigns.
