Avery Broderick: Perimeter Institute and University of Waterloo

Avery Broderick Perimeter Institute for Theoretical Physics

Dr. Avery Broderick will provide a highly accessible and interesting lecture on the Event Horizon Telescope (EHT) and international efforts to interpret horizon-resolving images of numerous supermassive black holes. Black holes are among the most powerful and mysterious phenomena in the universe. Almost every galaxy has at its core a supermassive black hole, millions or even billions of times more massive than our sun. Despite composing a small fraction of the galactic mass budgets, they set the stage for astrophysical dramas that dictate the fates of their hosts.

Photons from the Edge: Revealing Black Holes with the Event Horizon Telescope

Avery Broderick Perimeter Institute for Theoretical Physics
The Event Horizon Telescope, global array of millimetre telescopes, has now enabled studies of nearby supermassive black holes on sub-horizon length scales. This unprecedented access opens a window onto not only the high-energy astrophysics of black hole accretion and jet formation, but also the nature of gravity in the heretofore unexplored strongly non-linear regime near the black hole horizon.

EHT Constraints on Jet Launching in M87

Avery Broderick Perimeter Institute for Theoretical Physics
Because of the existence of a prominent jet, M87 provides an ideal source with which the EHT can critically test current jet launching paradigms. The EHT has already placed weak limits on the black hole spin based on generic arguments regarding limits on the image size. However, careful modeling of the jet structure can produce much more stringent constraints on both the black hole properties and the mechanisms responsible for the generation of the observed radio emission.
