We report results of numerical relativity simulations for 26 new nonspinning binary neutron star systems with 6 grid resolutions using an adaptive mesh refinement numerical relativity code SACRA-MPI. The finest grid spacing is approximate to 64-85...
New viscous neutrino-radiation hydrodynamics simulations are performed for accretion disks surrounding a spinning black hole with low mass 3 M-circle dot and dimensionless spin 0.8 or 0.6 in full general relativity, aiming at modeling the evolutio...

We find that the Hanford and Livingston detectors of Advanced LIGO derive a distinct posterior probability distribution of binary tidal deformability (Lambda) over tilde of the first binary-neutron-star merger GW170817. By analyzing public data of...
The location of the cutoff in the gravitational-wave spectrum of black
hole-neutron star mergers is correlated strongly with the neutron-star radius
for the case that the neutron star is disrupted by the black hole during the
merger. However, the ...
