Introducing Rachael Alexandroff

I am  Rachael Alexandroff, an NSERC postdoctoral fellow in observational extragalactic astronomy with a joint appointment at the Canadian Institute for Theoretical Astrophysics and the Dunlap Institute for Astronomy and Astrophysics.

My research interests focus primarily on extragalactic astronomy. In particular, I am interested in exploringfeedback from actively accreting supermassive black holes (quasars) using a variety of multi-wavelength data in the radio to the X-ray. I previously identified the largest catalog of optically-selected obscured quasars in the early Universe and have been using this catalog to study how quasars effect their surroundings from the local environment to the entire host galaxy. In particular, I search for observational signatures of quasar feedback to help constrain models of galaxy evolution. You can read more here.

In particular, I love to solve interesting problems using a combination of large datasets and targeted observations to elucidate the underlying physics. By constructing models and digging out fundamental correlations we can come to understand the physical principles that govern the myriad disparate observations we are trying to analyze.

I obtained my graduate degree on July 18, 2017 from Johns Hopkins University’s Department of Physics and Astronomy working for Prof. Nadia Zakamska. Previously, I obtained a bachelor of arts in astrophysical sciences from Princeton University.

I am also very passionate about astronomy education and outreach and am president emeritus of the Physics and Astronomy Graduate Student Outreach group at Johns Hopkins University. I have spoken to groups of 500+ audience members at Astronomy on Tap Toronto and given talks at local libraries, high schools and community centres.
