Hunting for Gravitational Wave Counterparts

Since the groundbreaking first detection of merging neutron stars in gravitational waves and electromagnetic radiation in August 2017, researchers at Stockholm University have continued to search for electromagnetic counterparts – bright transient sources in the sky – in connection with gravitational-wave events.
