Prospects for characterizing Population III remnants with next-generation gravitational-wave observatories
N. V. Krishnendu, Patricia Schmidt, Geraint Pratten
The most distant gravitational-wave (GW) detection by LIGO, Virgo and KAGRA so far is a binary black hole (BBH) merger at a redshift of , corresponding to a luminosity d…
Binary black hole scattering with generic spins
Adam Clark, Geraint Pratten, Patricia Schmidt
In this Letter, we confront high-order post-Minkowskian (PM) predictions for generic-spin black-hole scattering with numerical-relativity (NR) simulations for the first time, targe…
Post-Newtonian inspiral waveform model for eccentric precessing binaries with higher-order modes and matter effects
Gonzalo Morras, Geraint Pratten, Patricia Schmidt +1
We introduce pyEFPEHM, a post-Newtonian (PN) inspiral waveform model for eccentric and spin-precessing compact binaries that includes higher-order modes and matter effects. Accurat…
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…
Impact of eccentricity on the population properties of neutron star - black hole mergers
Gonzalo Morras, Geraint Pratten, Patricia Schmidt
We revisit the population properties of neutron star-black hole (NSBH) mergers using low-mass compact binary coalescences reported through GWTC-4. Employing pyEFPE, an inspiral-onl…
Orbital eccentricity in a neutron star - black hole merger
Gonzalo Morras, Geraint Pratten, Patricia Schmidt
The observation of gravitational waves from merging black holes and neutron stars provides a unique opportunity to discern information about their astrophysical environment. Two si…
