"How colliding black holes allow us to hear gravity: an introduction to gravitational wave astronomy."

by Lieke van Son, Ph.D. Candidate at the Center for Astronomy at Harvard

Abstract: On the 14th of September of 2015, for the first time in human history, we managed to observe what are called “gravitational waves”:  ripples in space time that had travelled more than a billion years to reach us here on earth, caused by the collision of two black holes. This direct detection of gravitational waves heralded a whole new era in astronomy, literally unveiling parts of the Universe to which we were blind before. Moreover, back in 2015 astronomers assumed that such detections would be rare, however, today we observe one about every week!
In this colloquium I will give a short introduction to gravitational wave astronomy: what are gravitational waves,  how do we detect them and where do they come from? I will discuss some of the exciting science that has been done, and will be possible in the near future, with a focus on massive stellar binaries as plausible progenitors.
