External Inverse-Compton Emission Associated with Extended and Plateau Emission of Short Gamma-Ray Bursts: Application to GRB 160821B
B. Theodore Zhang, Kohta Murase, Chengchao Yuan +2
The recent detection of TeV photons from two gamma-ray bursts (GRBs), GRB 190114C and GRB 180720B, has opened a new window for multi-messenger and multi-wavelength astrophysics of…
Post-Merger Jets from Supermassive Black Hole Coalescences as Electromagnetic Counterparts of Gravitational Wave Emission
Chengchao Yuan, Kohta Murase, B. Theodore Zhang +2
As a powerful source of gravitational waves (GW), a supermassive black hole (SMBH) merger may be accompanied by a relativistic jet that leads to detectable electromagnetic (EM) emi…
External Inverse-Compton Emission from Low-Luminosity Gamma-Ray Bursts: Application to GRB 190829A
B. Theodore Zhang, Kohta Murase, Péter Veres +1
The detection of TeV gamma-ray bursts (GRBs) brought new opportunities for studying the physics of particle acceleration at relativistic shocks. The \hess telescopes recently obser…
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…
Neutron conversion-diffusion: a new model for structured short gamma-ray burst jets compatible with GRB 170817
Edwan Préau, Kunihito Ioka, Peter Mészáros
We present a generic theoretical model for the structuring of a relativistic jet propagating through the ejecta of a binary neutron star merger event, introducing the effects of th…
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-…
