Mass Ratio of Binary Black Holes Determined from LIGO/Virgo Data Restricted to Small False Alarm Rate

Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano

We focus on gravitational-wave events of binary black-hole mergers up to the third observing run with the minimum false alarm rate smaller than $10^{-5}{\mathrm{yr}}^{-1}$. These even…
