Self-consistent picture of the mass ejection from a one second-long binary neutron star merger leaving a short-lived remnant in general-relativistic neutrino-radiation magnetohydrodynamic simulation
Kenta Kiuchi, Sho Fujibayashi, Kota Hayashi +3
We perform a general-relativistic neutrino-radiation magnetohydrodynamic simulation of a one second-long binary neutron star merger on Japanese supercomputer Fugaku using about $72…
General-relativistic neutrino-radiation magnetohydrodynamics simulation of seconds-long black hole-neutron star mergers: Dependence on initial magnetic field strength, configuration, and neutron-star equation of state
Kota Hayashi, Kenta Kiuchi, Koutarou Kyutoku +2
As a follow-up study of our previous work, numerical-relativity simulations for seconds-long black hole-neutron star mergers are performed for a variety of setups. Irrespective of…
Quasinormal modes of Schwarzschild black holes on the real axis
Koutarou Kyutoku, Hayato Motohashi, Takahiro Tanaka
We study the scattering of gravitational waves by a Schwarzschild black hole and its perturbed siblings to investigate influences of proposed spectral instability of quasinormal mo…
Gravitational Wave Signal for Quark Matter with Realistic Phase Transition
Yuki Fujimoto, Kenji Fukushima, Kenta Hotokezaka +1
The cores of neutron stars (NSs) near the maximum mass realize the most highly compressed matter in the universe where quark degrees of freedom may be liberated. Such a state of de…
Comprehensive study of mass ejection and nucleosynthesis in binary neutron star mergers leaving short-lived massive neutron stars
Sho Fujibayashi, Kenta Kiuchi, Shinya Wanajo +3
By performing general relativistic hydrodynamics simulations with an approximate neutrino-radiation transfer, the properties of ejecta in dynamical and post-merger phases are inves…
How many extra-Galactic stellar-mass binary black holes will be detected by space gravitational-wave interferometers?
Naoki Seto, Koutarou Kyutoku
On the basis of GWTC-3, we discuss the detection prospect of extra-Galactic binary black holes (BBHs) by space gravitational-wave interferometers. In particular, targeting BBHs wit…
