Quasar Astrophysics, Multi-messager Astronomy, and What We are Doing Now, Before LISA Flies
Presented by Nicholas Ross
Institute for Astronomy, University of Edinburgh

Thursday, July 25, 2019
11:00 A.M. in 169-336

Abstract
With now over 20 gravitational wave events detected by the LIGO/Virgo Consortium, direct observational gravitational wave astronomy is in full operation. Meanwhile, new large time-domain EM surveys (e.g., ZTF, NEOWISE and in the very near future LSST) are being data-mined to discover new astrophysical phenomena, or understand in greater detail processes that are fundamental to astrophysics (e.g. accretion onto compact objects). In this talk, I'll give an update and overview into the latest work (and interpretation) of the "Changing Look quasar" AGN population, and connect these to the latest LIGO "O3" results, including a focus on their infrared properties. We will also look ahead to the near-future ground and space-based missions that will tie together the gravitational and electromagnetic signatures of accreting black holes.
