Acceleration and Escape Processes of High-energy Particles in Turbulence inside Hot Accretion Flows
Shigeo S. Kimura, Kengo Tomida, Kohta Murase
We investigate acceleration and propagation processes of high-energy particles inside hot accretion flows. The magnetorotational instability (MRI) creates turbulence inside accreti…
Delayed jet breakouts from binary neutron star mergers
Tatsuya Matsumoto, Shigeo S. Kimura
Short gamma-ray bursts (sGRBs) are thought to be produced by binary NS mergers. While a sGRB requires a relativistic jet to break out of ejecta, the jet may be choked and fails to…
Super-Knee Cosmic Rays from Galactic Neutron Star Merger Remnants
Shigeo S. Kimura, Kohta Murase, Peter Mészáros
The detection of gravitational waves and electromagnetic counterparts from a binary neutron star (BNS) merger confirmed that it is accompanied by the launch of fast merger ejecta.…
Trans-Ejecta High-Energy Neutrino Emission from Binary Neutron Star Mergers
Shigeo S. Kimura, Kohta Murase, Imre Bartos +3
The observations of a macronova/kilonova accompanied by gravitational waves from a binary neutron star merger (GW170817) confirmed that neutron star coalescences produce copious ej…
