Dr. Rachael Alexandroff

Rachael Alexandroff studies feedback from actively accreting supermassive black holes (quasars) using a variety of multi-wavelength data in 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.

Rachael received her PhD from Johns Hopkins University in July of 2017 after completing her undergraduate degree at Princeton University in 2012. She joined the Dunlap Institute as an NSERC Postdoctoral Fellow in September 2017.
