Riverdale Library: Science Literacy Week: Black Holes
Join us for a fascinating Science Literacy Week lecture presented by Dr. Rachael Alexandroff, PhD, an expert on black holes and researcher at the Dunlap Institute for Astronomy & Astrophysics at the University of Toronto.
Dr. Alexandroff studies feedback from actively accreting supermassive black holes (quasars) using a variety of multi-wavelength data from the radio to the X-ray. She previously identified the largest catalog of optically-selected obscured quasars in the early Universe and has been using this catalog to study how quasars effect their surroundings from the local environment to the entire host galaxy. In particular, she searches for observational signatures of quasar feedback to help constrain semi-analytic models of galaxy evolution.
At the Dunlap, Rachael is interested in expanding her work on the radio properties of so-called radio-quiet, luminous quasars to study the energetics and effect of quasar winds on galaxy evolution and to search for dual supermassive black hole candidates in galaxy mergers.
