Probing Binary Black Hole Environments in Hierarchical Triple Systems
Lisa Randall, Harvard University,

With the recent LIGO results it has been clear that we can learn a lot about the distribution of binary black hole systems.
Yet the origin of these black holes is still unknown. Do they come from galactic centers, globular clusters, or from more isolated regions of a galaxy?  In this talk I discuss how we can hope to measure eccentricity in LIGO and more direct phase shift and orbital motion measurements in LISA, as a step towards disentangling these possibilities. We show how to analytically approximate eccentricity distributions for systems with slow Kozai-Lidov evolution.
