Title: What can we learn from gravitational waves of binary black hole mergers that include remnant kicks?
Abstract: Remnants of binary black-hole mergers can gain significant recoil or kick velocities when the binaries are asymmetric, which may leave a characteristic imprint in the observed signal. So far, only one gravitational-wave event supports a nonzero kick velocity: GW200129_065458. Interestingly, this signal is also the first to show evidence of spin precession. For most other gravitational-wave observations, spin orientations are poorly constrained as this would require large signal-to-noise ratios, unequal mass ratios, or inclined systems. In this talk, I will discuss how large kicks can help to extract more information about their sources.
