High-velocity collision of two black holes
Masaru Shibata, Hirotada Okawa, Tetsuro Yamamoto
We study nonaxisymmetric collision of two black holes (BHs) with a high velocity -- at infinity, where denotes four-dimensional coordinates. We prepa…
Accurate evolutions of inspiralling neutron-star binaries: prompt and delayed collapse to black hole
Luca Baiotti, Bruno Giacomazzo, Luciano Rezzolla
Binary neutron-star (BNS) systems represent primary sources for the gravitational-wave (GW) detectors. We present a systematic investigation in full GR of the dynamics and GW emiss…
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…
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…
Supernova light curve models for the bump in the Optical Counterpart of X-Ray Flash 030723
N. Tominaga, J. Deng, P. A. Mazzali +5
XRF 030723 is the first X-ray flash (XRF) to show in its optical light curve (LC) a bump that has been interpreted as the signature of a supernova (SN). After subtracting the after…
Molecular Discreteness in Reaction-Diffusion Systems Yields Steady States Not Seen in the Continuum Limit
Yuichi Togashi, Kunihiko Kaneko
We investigate the effects of spatial discreteness of molecules in reaction-diffusion systems. It is found that discreteness within the so called Kuramoto length can lead to a loca…
