Electromagnetic Counterparts of Neutron Star Mergers - Past and Future

The discovery of GW150914 begun the era of gravitational wave astronomy. An electromagnetic signal accompanying a GW signal could significantly enhance the information that can be obtained from such events. I review the importance of such detection and two such major sources of electromagnetic emission from neutron star mergers – macronova and radio flares. I will discuss observations of several recent macronova and radio-flares and   prospects of detections of these transients in the  future.
