On Thursday, 2018-03-29 at 13:30 in the Physics & Astronomy Seminar Room 100
there will be a talk by

Dr. Niayesh Afshordi
Department of Physics and Astronomy
University of Waterloo
and Perimeter Institute for Theoretical Physics

on the topic
“Quantum Black Holes in the Sky: from Quantum Gravity to Astrophysics and Cosmology”

In classical General Relativity (GR), an observer falling into an astrophysical black hole (BH) is not expected to experience anything dramatic as she crosses the event horizon. However, tentative resolutions to problems in quantum gravity, such as the cosmological constant problem or the black hole information paradox, invoke significant departures from classicality in the vicinity of the horizon. Theoretical and phenomenological arguments for these departures will be outlined. Tentative observational evidence for Planck-scale structure near BH horizons will be discussed, seen as “echoes” in gravitational wave observations, which has now been found by three independent groups. Finally, how gravitational wave echoes can teach us about the fate of the binary neutron star merger, recently discovered by gravitational wave and electromagnetic observations will be explained.

This lecture sounds fascinating! Is this lecture held at UWO? Is it open to non-students? Sorry if you have already answered these questions before, I am fairly new to London RASC. I appreciate any insight that you can give me. Thanks in advance! :)

Yes, it's at the University campus. Info in the original post, or available on the Physics & Astronomy website.

Always a good idea to check there anyway -- last week's lecture was cancelled, for instance.

Hope to see you there!
