Merger of black hole and neutron star in general relativity: Tidal disruption, torus mass, and gravitational waves
Masaru Shibata, Keisuke Taniguchi
We systematically perform the merger simulation of black hole-neutron star (BH-NS) binaries in full general relativity, focusing on the case that the NS is tidally disrupted. We pr…
Future plan for observation of cosmic gamma rays in the 100 TeV energy region with the Tibet air shower array : physics goal and overview
M. Amenomori, X. J. Bi, D. Chen +82
The Tibet air shower array, which has an effective area of 37,000 square meters and is located at 4300 m in altitude, has been observing air showers induced by cosmic rays with ene…

Magnetohydrodynamics of Neutrino-Cooled Accretion Tori around a Rotating Black Hole in General Relativity
M. Shibata, Y. Sekiguchi, R. Takahashi
We present our first numerical results of axisymmetric magnetohydrodynamic simulations for neutrino-cooled accretion tori around rotating black holes in general relativity. We cons…
A Formation Mechanism of Collapsar Black Hole -- early evolution phase
Yuichiro Sekiguchi, Masaru Shibata
The latest studies of massive star evolution indicate that an initially rapidly rotating star with sufficiently low metallicity can produce a rapidly rotating, massive stellar core…
The Final Fate of Binary Neutron Stars: What Happens After the Merger?
Matthew D. Duez, Yuk Tung Liu, Stuart L. Shapiro +2
The merger of two neutron stars usually produces a remnant with a mass significantly above the single (nonrotating) neutron star maximum mass. In some cases, the remnant will be st…
