An arm length stabilization system for KAGRA and future gravitational-wave detectors
T. Akutsu, M. Ando, K. Arai +198
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the a…
Reanalysis of the binary neutron star mergers GW170817 and GW190425 using numerical-relativity calibrated waveform models
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We reanalyze gravitational waves from binary-neutron-star mergers GW170817 and GW190425 using a numerical-relativity (NR) calibrated waveform model, the TF2+_Kyoto model, which inc…
Diversity of kilonova light curves
Kyohei Kawaguchi, Masaru Shibata, Masaomi Tanaka
We perform radiative transfer simulations for kilonova in various situations, including the cases of prompt collapse to a black hole from neutron-star mergers, high-velocity ejecta…
Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
Sub-radian-accuracy gravitational waves from coalescing binary neutron stars II: Systematic study on the equation of state, binary mass, and mass ratio
Kenta Kiuchi, Kyohei Kawaguchi, Koutarou Kyutoku +2
We report results of numerical relativity simulations for {\it new} 26 non-spinning binary neutron star systems with 6 grid resolutions using an adaptive mesh refinement numerical…
Systematic Opacity Calculations for Kilonovae
Masaomi Tanaka, Daiji Kato, Gediminas Gaigalas +1
Coalescence of neutron stars gives rise to kilonova, thermal emission powered by radioactive decays of freshly synthesized r-process nuclei. Although observational properties are l…
Short GRB 160821B: a reverse shock, a refreshed shock, and a well-sampled kilonova
G. P. Lamb, N. R. Tanvir, A. J. Levan +31
We report our identification of the optical afterglow and host galaxy of the short-duration gamma-ray burst GRB 160821B. The spectroscopic redshift of the host is , making…
