Simulation-based Inference for Gravitational Waves from Binary Neutron Stars: Application of Summary Data from Heterodyning
Masaki Iwaya, Vivien Raymond, Soichiro Morisaki +1
Gravitational-wave parameter estimation for binary neutron star (BNS) systems poses severe computational challenges due to the extended signal duration, which can reach several min…
Simulation-based Inference towards Gravitational-wave waveform systematics in Intermediate-Mass Binary Black Holes
Sama Al-Shammari, Alexandre Göttel, Masaki Iwaya +1
Parameter estimation for gravitational-wave signals is computationally demanding due to the high dimensionality of the parameter space and the cost of repeated waveform generation…
Gravitational-wave Observations Suggest Most Black Hole Mergers Form in Triples
Jakob Stegmann, Fabio Antonini, Aleksandra Olejak +4
The spin-orbit tilt angles of merging stellar-mass black holes provide key insights into their astrophysical origin. Non-parametric population modelling of The LIGO, Vir…
Fast and Precise Spectral Analysis for Dark Matter Searches with LIGO
Alexandre Göttel, Vivien Raymond
We introduce a novel logarithmic spectral estimation method for dark matter searches using gravitational-wave detectors, integrating established dark matter search techniques with…
Real-time gravitational-wave inference for binary neutron stars using machine learning
Maximilian Dax, Stephen R. Green, Jonathan Gair +7
Mergers of binary neutron stars (BNSs) emit signals in both the gravitational-wave (GW) and electromagnetic (EM) spectra. Famously, the 2017 multi-messenger observation of GW170817…
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…
Simulation-based Inference for Gravitational-waves from Intermediate-Mass Binary Black Holes in Real Noise
Vivien Raymond, Sama Al-Shammari, Alexandre Göttel
We present an exploratory investigation into using Simulation-based Inference techniques, specifically Flow-Matching Posterior Estimation, to construct a posterior density estimato…
Bayesian inference for compact binary coalescences with BILBY: Validation and application to the first LIGO--Virgo gravitational-wave transient catalogue
I. M. Romero-Shaw, C. Talbot, S. Biscoveanu +56
Gravitational waves provide a unique tool for observational astronomy. While the first LIGO--Virgo catalogue of gravitational-wave transients (GWTC-1) contains eleven signals from…
Going the Distance: Mapping Host Galaxies of LIGO and Virgo Sources in Three Dimensions Using Local Cosmography and Targeted Follow-up
L. P. Singer, H. -Y. Chen, D. E. Holz +17
The Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) discovered gravitational waves (GWs) from a binary black hole merger in 2015 September and may soon observe…
