Upscattered Cocoon Emission in Short Gamma-ray Bursts as High-energy Gamma-ray Counterparts to Gravitational Waves
Shigeo S. Kimura, Kohta Murase, Kunihito Ioka +3
We investigate prolonged engine activities of short gamma-ray bursts (SGRBs), such as extended and/or plateau emissions, as high-energy gamma-ray counterparts to gravitational wave…
Multi-messenger tests of cosmic-ray acceleration in radiatively inefficient accretion flows
Shigeo S. Kimura, Kohta Murase, Peter Mészáros
The cores of active galactic nuclei (AGNs) have been suggested as the sources of IceCube neutrinos, and recent numerical simulations have indicated that hot AGN coronae of Seyfert…
Hidden Cores of Active Galactic Nuclei as the Origin of Medium-Energy Neutrinos: Critical Tests with the MeV Gamma-Ray Connection
Kohta Murase, Shigeo S. Kimura, Peter Meszaros
Mysteries about the origin of high-energy cosmic neutrinos have deepened by the recent IceCube measurement of a large diffuse flux in the 10-100 TeV range. Based on the standard di…
High-energy emissions from neutron star mergers
Shigeo S. Kimura
In 2017, LIGO-Virgo collaborations reported detection of the first neutron star merger event, GW170817, which is accompanied by electromagnetic counterparts from radio to gamma ray…
