Gravitational Wave Hyperbolic Catalog: Reanalyzing High-Mass Gravitational Wave Signals Using Hyperbolic Waveforms

In regions with dense stellar remnants such as: globular clusters; galactic nuclei; and active galactic nuclei disks, unbound pairs are thought undergo hyperbolic scattering and dynamical capture. Encounters of two black holes on unbound orbits resulting in mergers produce unique waveform morphologies that can be similar to those from high mass, quasi-circular coalescences. In this work, we reanalyze high mass, publicly-available LIGO-Virgo-KAGRA signals with the hyperbolic model: TEOBResumS-Dalí including higher order modes and non-precessing spins. In order to quantify the significance, we compare them with those found using the same model under a quasi-circular, spin-precessing hypothesis and calculate a the Bayes Factor between the two scenarios. We report any significant preference for hyperbolic encounters as well as any effects on the inferred parameters due to the hyperbolic orbital geometry.
