Title: Setting the Stage for the Era of Gravitational Wave Discovery
Speaker: Wen-fai Fong, University of Arizona
Host: Vicky Kalogera, Niharika Sravan, and Fani Dosopoulou
Abstract:
The first advanced gravitational wave detectors are newly operational and have brought of the most anticipated discoveries of the century: the direct detection of gravitational waves. The premier gravitational wave sources are the mergers of two compact objects, involving either two neutron stars or a neutron star and a black hole. While the gravitational wave signal will give insight to the basic properties of compact objects, a coincident detection at electromagnetic wavelengths will significantly leverage the event by providing precise sky localization and an association to a galaxy. The main challenge will be how to identify the correct electromagnetic counterpart amidst an otherwise dynamic sky. In this talk, I discuss ongoing efforts to characterize the electromagnetic signatures from compact object mergers. In particular, I present observational evidence linking mergers to two distinct counterparts: short-duration gamma-ray bursts (GRBs) and long-lived transients powered by the radioactive decay of heavy elements (kilonovae). I then address how these results can help us develop observing strategies for this revolutionary era of gravitational wave discovery.
