Properties of black hole-star binaries formed in -body simulations of massive star clusters: implications for Gaia black holes
Federico Fantoccoli, Jordan Barber, Fani Dosopoulou +2
We investigate black hole-star binaries formed in -body simulations of massive, dense star clusters. We simulate 32 clusters with varying initial masses (…
The Impact of Astrophysical Priors on Parameter Inference for GW230529
Debatri Chattopadhyay, Sama Al-Shammari, Fabio Antonini +3
We investigate the effects of prior selection on the inferred mass and spin parameters of the neutron star-black hole merger GW230529\_181500. Specifically, we explore models motiv…
Binary population synthesis of the Galactic canonical pulsar population
Yuzhe Song, Simon Stevenson, Debatri Chattopadhyay +2
Pulsars are rapidly rotating neutron stars that emit radiation across the electromagnetic spectrum, from radio to gamma-rays. We use the rapid binary population synthesis suite COM…
Reconstructing the Genealogy of LIGO-Virgo Black Holes
Parthapratim Mahapatra, Debatri Chattopadhyay, Anuradha Gupta +4
We propose a Bayesian inference framework to predict the merger history of LIGO-Virgo binary black holes (BHs), whose binary components may have undergone hierarchical mergers in t…
Everything everywhere all at once: A detailed study of GW230529
Koustav Chandra, Ish Gupta, Rossella Gamba +5
This study investigates the origins of GW230529, delving into its formation from massive stars within isolated binary systems. Utilizing population synthesis models, we present com…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
