TeV Gamma Rays and Neutrinos from Winds Driven by Radiatively Inefficient Accretion Flows of Low-Luminosity Active Galactic Nuclei
Nobuyuki Sakai, John F. Beacom, Kohta Murase
Recently, the Large High Altitude Air Shower Observatory (LHAASO) reported the first TeV gamma-ray detection from a low-luminosity active galactic nucleus (LLAGN) lacking a strong…
The Disk Wind Contribution to the Gamma-Ray emission from the nearby Seyfert Galaxy GRS 1734-292
Nobuyuki Sakai, Tomoya Yamada, Yoshiyuki Inoue +4
Radio-quiet Seyfert galaxies have been detected in GeV gamma-rays by the Large Area Telescope (LAT), but the origin of much of this emission is unclear. We consider the nea…
Neutrinos and gamma rays from beta decays in an active galactic nucleus NGC 1068 jet
Koichiro Yasuda, Nobuyuki Sakai, Yoshiyuki Inoue +1
We show that TeV neutrinos and high-energy gamma rays detected from the nearby active galaxy NGC 1068 can simultaneously be explained in a model based on the beta decays of neutron…
Deciphering Radio Emissions from Accretion Disk Winds in Radio-Quiet Active Galactic Nuclei
Tomoya Yamada, Nobuyuki Sakai, Yoshiyuki Inoue +1
Unraveling the origins of radio emissions from radio-quiet active galactic nuclei (RQ AGNs) remains a pivotal challenge in astrophysics. One potential source of this radiation is t…
