High-energy neutrino emission subsequent to gravitational wave radiation from supermassive black hole mergers
Chengchao Yuan, Kohta Murase, Shigeo S. Kimura +1
Supermassive black hole (SMBH) coalescences are ubiquitous in the history of the Universe and often exhibit strong accretion activities and powerful jets. These SMBH mergers are al…
Deciphering the Origin of the GeV--TeV Gamma-ray Emission from SS 433
Shigeo S. Kimura, Kohta Murase, Peter Mészáros
We investigate hadronic and leptonic scenarios for the GeV--TeV gamma-ray emission from jets of the microquasar SS 433. The emission region of the TeV photons coincides with the X-…
High-Energy Neutrino and Gamma-Ray Emission from Tidal Disruption Events
Kohta Murase, Shigeo S. Kimura, B. Theodore Zhang +2
Tidal disruption events (TDE) have been considered as cosmic-ray and neutrino sources for a decade. We suggest two classes of new scenarios for high-energy multi-messenger emission…
Hadronic High-energy Emission from Magnetically Arrested Disks in Radio Galaxies
Shigeo S. Kimura, Kenji Toma
We propose a novel interpretation that gamma-rays from nearby radio galaxies are hadronic emission from magnetically arrested disks (MADs) around central black holes (BHs). The mag…
Linking extended and plateau emissions of short gamma-ray bursts
Tatsuya Matsumoto, Shigeo S. Kimura, Kohta Murase +1
Some short gamma-ray bursts (SGRBs) show a longer lasting emission phase, called extended emission (EE) lasting , as well as a plateau emission (PE) lasting $…
