The Origin of Binary Black Holes Mergers

Understand

Recently Venumadhav et al.

• (2019) proposed a new pipeline to analyze LIGO-Virgo's O1-O2 data and discovered eight new binary black hole (BBH) mergers, including a high effective spin, chi_{eff}, one.
• This discovery sheds new light on the origin of the observed BBHs and the dynamical capture vs.
• field binaries debate.
