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…
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, Vi…
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…
Simulation-based Inference for Gravitational-waves from Intermediate-Mass Binary Black Holes in Real Noise
