Black hole mergers and blue stragglers from hierarchical triples formed in globular clusters

F Antonini, S Chatterjee, CL Rodriguez… - The Astrophysical …, 2016 - iopscience.iop.org
Hierarchical triple-star systems are expected to form frequently via close binary–binary

Eccentric black hole gravitational-wave capture sources in galactic nuclei: Distribution of binary parameters

L Gondán, B Kocsis, P Raffai, Z Frei - The Astrophysical Journal, 2018 - iopscience.iop.org
Mergers of binary black holes on eccentric orbits are among the targets for second-

Measuring eccentricity in binary black hole inspirals with gravitational waves

ME Lower, E Thrane, PD Lasky, R Smith - Physical Review D, 2018 - APS
When binary black holes form in the field, it is expected that their orbits typically circularize
before coalescence. In galactic nuclei and globular clusters, binary black holes can form …

Constraining the orbital eccentricity of inspiralling compact binary systems with Advanced LIGO

M Favata, C Kim, KG Arun, JC Kim, HW Lee - Physical Review D, 2022 - APS
The detection of∼ 50 coalescing compact binaries with the Advanced LIGO and Virgo
detectors has allowed us to test general relativity, constrain merger rates, and look for …

Complete waveform model for compact binaries on eccentric orbits

EA Huerta, P Kumar, B Agarwal, D George, HY Schive… - Physical Review D, 2017 - APS
We present a time domain waveform model that describes the inspiral, merger and ringdown
of compact binary systems whose components are nonspinning, and which evolve on orbits …

High eccentricities and high masses characterize gravitational-wave captures in galactic nuclei as seen by Earth-based detectors

L Gondán, B Kocsis - Monthly Notices of the Royal Astronomical …, 2021 - academic.oup.com
The emission of gravitational waves (GWs) during single–single close encounters in galactic
nuclei (GNs) leads to the formation and rapid merger of highly eccentric stellar-mass black …

Blind spots and biases: The dangers of ignoring eccentricity in gravitational-wave signals from binary black holes

Divyajyoti, S Kumar, S Tibrewal, IM Romero-Shaw… - Physical Review D, 2024 - APS
Most gravitational wave (GW) events observed so far by the LIGO and Virgo detectors are
consistent with mergers of binary black holes (BBHs) on quasicircular orbits. However, some …
