Binary black holes in the heat of merger
Samanwaya Mukherjee, Sayak Datta, Sukanta Bose +1
A black hole binary approaching merger undergoes changes in its inspiral rate as energy and angular momentum are lost from the orbits into the horizons. This effect strengthens as…
Detection of GW200105 with a targeted eccentric search
Khun Sang Phukon, Patricia Schmidt, Gonzalo Morras +1
The neutron star -- black hole (NSBH) binary GW200105 was recently found to have significant residual orbital eccentricity at a gravitational-wave frequency of 20 Hz~\cite{Morras:2…
Compact Binary Coalescence Sensitivity Estimates with Injection Campaigns during the LIGO-Virgo-KAGRA Collaborations' Fourth Observing Run
Reed Essick, Michael W. Coughlin, Michael Zevin +21
We describe the effort to characterize gravitational-wave searches and detector sensitivity to different types of compact binary coalescences during the LIGO-Virgo-KAGRA Collaborat…
Evolution of precessing binary black holes on eccentric orbits using orbit-averaged evolution equations
Khun Sang Phukon, Nathan K. Johnson-McDaniel, Amitesh Singh +1
The most general bound binary black hole (BBH) system has an eccentric orbit and precessing spins. The detection of such a system with significant eccentricity close to the merger…
Tracing the evolution of eccentric precessing binary black holes: a hybrid approach
Amitesh Singh, Nathan K. Johnson-McDaniel, Anuradha Gupta +1
To describe a general bound binary black hole system, we need to consider orbital eccentricity and the misalignment of black holes' spin vectors with respect to the orbital angular…
A geometric template bank for the detection of spinning low-mass compact binaries with moderate orbital eccentricity
Khun Sang Phukon, Patricia Schmidt, Geraint Pratten
Compact binaries on eccentric orbits are another class of gravitational-wave (GW) sources that can provide a wealth of information on binary formation pathways and astrophysical en…
