Indication for a compact object next to a LIGO-Virgo binary black hole merger

Published 3 Jan 2024 in astro-ph.HE and gr-qc | (2401.01743v1)

Abstract: The astrophysical origin of binary black hole (BBH) mergers remains uncertain though many events have been observed by the LIGO-Virgo-KAGRA network. Such mergers are predicted to originate in the vicinity of massive black holes (MBHs). Especially, GW190814, due to its secondary mass and mass ratio being beyond the expectations of isolated stellar evolution theories, is a promising event that has happened in an active galactic nucleus(AGN) disk. In this model, a compact object resides in the vicinity of a merging BBH. Here we report multiple pieces of evidence pointing to the fact that GW190814 is a BBH merging near a compact object. The orbital motion of BBHs around the third body produces a line-of-sight acceleration (LSA) and induces a varying Doppler shift. Using a waveform template that considers LSA, we perform Bayesian inference on a few BBH events with a high signal-to-noise ratio in the gravitational-wave transient catalog (GWTC). Compared to the model for isolated BBH mergers, we obtain significantly higher network signal-to-noise ratios for GW190814 by that with the LSA and constrain the LSA to $a = 0.0014{+0.0014}_{-0.0022} ~c~\mathrm{s}{-1}$. In addition, the logarithmic Bayes factor for the LSA case over the isolated case is $16.6$, which means the LSA model is significantly preferred by the GW data. We conclude that this is the first indication showing merging BBHs are located near a compact object.
