GW190521: A Binary Black Hole Merger with a Total Mass of $150M_{\odot }$

Abstract

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of $85_{-14}^{+21}{M}_{\odot }$ and $66_{-18}^{+17}{M}_{\odot }$ (90 % credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, and has only a 0.32 % probability of being below $65M_{\odot }$. We calculate the mass of the remnant to be $142_{-16}^{+28}{M}_{\odot }$, which can be considered an intermediate mass black hole (IMBH). The luminosity distance of the source is $5.3_{-2.6}^{+2.4}$ Gpc, corresponding to a redshift of $0.82_{-0.34}^{+0.28}$. The inferred rate of mergers similar to GW190521 is $0.13_{-0.11}^{+0.30}{\mathrm{Gpc}}^{-3}{\mathrm{yr}}^{-1}$.
