Correlation analysis of gravitational waves and neutrino signals to constrain neutrino flavor conversion in core-collapse supernova
Hiroki Nagakura, David Vartanyan
Recent multi-dimensional (multi-D) core-collapse supernova (CCSN) simulations characterize gravitational waves (GWs) and neutrino signals, offering insight into universal propertie…
Basic characteristics of neutrino flavor conversions in the post-shock regions of core-collapse supernova
Hiroki Nagakura, Masamichi Zaizen
One of the active debates in core-collapse supernova (CCSN) theory is how significantly neutrino flavor conversions induced by neutrino-neutrino self-interactions change the conven…
Dependence of weak interaction rates on the nuclear composition during stellar core collapse
Shun Furusawa, Hiroki Nagakura, Kohsuke Sumiyoshi +2
We investigate the influences of the nuclear composition on the weak interaction rates of heavy nuclei during the core collapse of massive stars. The nuclear abundances in nuclear…
Optical Synchrotron Precursors of Radio Hypernovae
Daisuke Nakauchi, Kazumi Kashiyama, Hiroki Nagakura +2
We examine the bright radio synchrotron counterparts of low-luminosity gamma-ray bursts (llGRBs) and relativistic supernovae (SNe) and find that they can be powered by spherical hy…
Jet collimation in the ejecta of double neutron star merger: new canonical picture of short gamma-ray bursts
Hiroki Nagakura, Kenta Hotokezaka, Yuichiro Sekiguchi +2
The observations of jet breaks in the afterglows of short gamma-ray bursts (SGRBs) indicate that the jet has a small opening angle of < 10°. The collimation mechanism of the jet is…
Relativistic Dissipative Accretion Flow onto Black Hole
Hiromi Saida, Rohta Takahashi, Hiroki Nagakura
Dissipations, e.g. heat flow and bulk and shear viscosities, cause the transport of energy, momentum and angular momentum, which is the essence of accretion of matters onto celesti…
