Little Red Dots as Hidden Neutrino Sources
Riku Kuze, Kunihito Ioka, Kohta Murase +2
Little Red Dots (LRDs) are enigmatic, compact, red galaxies at high redshift, -, discovered by the James Webb Space Telescope. Broad emission lines in the absence of X-…
Galactic Isolated Stellar-Mass Black Holes with the Magnetospheric Spark Gap as Possible GeV-TeV Gamma-ray Unidentified Sources
Koki Kin, Riku Kuze, Shigeo S. Kimura
Billions of isolated stellar-mass black holes (IBHs) are thought to wander through the interstellar medium (ISM) in the Galaxy, yet only one has been detected. IBHs embedded in ISM…
Multi-messenger Emission by Magnetically Arrested Disks and Relativistic Jets of Black Hole X-ray Binaries
Riku Kuze, Shigeo S. Kimura, Ke Fang
Black hole X-ray binaries (BHXBs) are observed in various wavelengths from radio to GeV gamma-ray. Several BHXBs, including MAXI J1820+070 and Cygnus X-1, are also found to emit ul…
Multi-wavelength Emission from Jets and Magnetically Arrested Disks in Nearby Radio Galaxies: Application to M87
Riku Kuze, Shigeo S. Kimura, Kenji Toma
Radio galaxies are a subclass of active galactic nuclei that drive relativistic jets from their center and are observed in radio to very-high-energy gamma rays. The emission mechan…
High-energy Gamma-rays from Magnetically Arrested Disks in Nearby Radio Galaxies
Riku Kuze, Shigeo S. Kimura, Kenji Toma
The origins of the GeV gamma-rays from nearby radio galaxies are unknown. Hadronic emission from magnetically arrested disks (MADs) around central black holes (BHs) is proposed as…
