How do you define eccentricity?
New paper with Aditya Vijayjumar and Alex Hanselman.
Black holes merging in the universe emit gravitational waves that we can detect. From these signals, we can tell how heavy the black holes were, how fast they were spinning, and how far away they merged. But there is another aspect of the signals that can be incredibly informing: orbital eccentricity, or how “stretched-out” the orbit is relative to a circular orbit.
