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…
Decadal upgrade strategy for KAGRA toward post-O5 gravitational-wave astronomy
KAGRA Collaboration, T. Akutsu, M. Ando +150
The KAGRA Collaboration has investigated a ten-year upgrade strategy for the KAGRA gravitational wave detector, considering a total of 14 upgrade options that vary in mirror mass,…
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 distributio…
