Neutrino and Cosmic-Ray Emission and Cumulative Background from Radiatively Inefficient Accretion Flows in Low-Luminosity Active Galactic Nuclei
Shigeo S. Kimura, Kohta Murase, Kenji Toma
We study high-energy neutrino and cosmic-ray (CR) emission from the cores of low-luminosity active galactic nuclei (LLAGN). In LLAGN, the thermalization of particles is expected to…
Circular polarization in the optical afterglow of GRB 121024A
K. Wiersema, S. Covino, K. Toma +37
Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…
Effects of High-Energy Particles on Accretion Flows onto a Supermassive Black Hole
Shigeo S. Kimura, Kenji Toma, Fumio Takahara
We study effects of high-energy particles on the accretion flows onto a supermassive black hole and luminosities of escaping particles such as protons, neutrons, gamma-rays, and ne…
Electromotive Force in the Blandford-Znajek Process
Kenji Toma, Fumio Takahara
One of the mechanisms widely considered for driving relativistic jets in active galactic nuclei, galactic microquasars, and gamma-ray bursts is the electromagnetic extraction of th…
