Title: "Formation of Black Hole Mergers in Dense Stellar Systems."
I will present recent results on how binary black holes (BBHs) merge in dense stellar systems through chaotic few-body interactions. By taking into account GR effects in the equation-of-motion, I will show that dense stellar systems are likely to produce non-circular (eccentric) mergers in both LISA and LIGO with rates that are 10-100 times larger than what have been reported over the past decades using Newtonian N-body codes. In particular, I will demonstrate using simple analytical arguments that 5-10% of all BBH mergers from classical globular clusters will be eccentric in LIGO. This makes eccentricity a promising parameter for distinguishing BBH merger channels from each other. I will further discuss new ideas related to how the BBH merger distribution indirectly can be mapped using interrupted stellar tidal disruptions.
