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…
Impact of Spin Priors on the Population Inference of Merging Binary Black Holes
Kazuya Kobayashi, Masaki Iwaya, Soichiro Morisaki +2
The spins of merging binary black holes (BBHs) inferred from gravitational-wave (GW) observations provide key insights into their formation channels. However, spin parameters are t…
Identification of Noise-Associated Glitches in KAGRA O3GK with Hveto
T. Akutsu, M. Ando, M. Aoumi +148
Transient noise ("glitches") in gravitational wave detectors can mimic or obscure true signals, significantly reducing detection sensitivity. Identifying and excluding glitch-conta…
An analytical joint prior for effective spins for inference on the spin distribution of binary black holes
Masaki Iwaya, Kazuya Kobayashi, Soichiro Morisaki +2
We derive an analytical form of the joint prior of effective spin parameters, and , assuming an isotropic and uniform-in-magnitude spin distribution.…
