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.…
Modification on thermal motion in Geant4 for neutron capture simulation in Gadolinium loaded water
Y. Hino, K. Abe, R. Asaka +10
Neutron tagging is a fundamental technique for electron anti-neutrino detection via the inverse beta decay channel. A reported discrepancy in neutron detection efficiency between o…
Implementation and investigation of electron-nucleus scattering in the \textsc{NEUT} neutrino event generator
Seisho Abe
Understanding nuclear effects is essential for improving the sensitivity of neutrino oscillation measurements. Validating nuclear models solely through neutrino scattering data is…
Parameter estimation of protoneutron stars from gravitational wave signals using the Hilbert-Huang transform
Seiya Sasaoka, Yusuke Sakai, Diego Dominguez +5
Core-collapse supernovae (CCSNe) are potential multimessenger events detectable by current and future gravitational wave (GW) detectors. The GW signals emitted during these events…
Characteristics of temporal variability of long-duration bursts of high-energy radiation associated with thunderclouds on the Tibetan plateau
H. Tsuchiya, K. Hibino, K. Kawata +9
From 1998 to 2017, neutron monitors located at an altitude of 4300 m on the Tibetan plateau detected 127 long-duration bursts of high-energy radiation in association with thundercl…
Black hole-neutron star mergers with massive neutron stars in numerical relativity
Shichuan Chen, Luohan Wang, Kota Hayashi +3
We study the merger of black hole-neutron star (BH-NS) binaries in numerical relativity, focusing on the properties of the remnant disk and the ejecta, varying the mass of compactn…
