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…
