Observable signatures of stellar-mass black holes in active galactic nuclei
Hiromichi Tagawa, Shigeo S. Kimura, Zoltán Haiman +2
Stellar-mass black holes (BHs) are predicted to be embedded in the disks of active galactic nuclei (AGN) due to gravitational drag and in-situ star formation. However, clear eviden…
Magnetic Reconnection in Black-Hole Magnetospheres: Lepton Loading into Jets, Superluminal Radio Blobs, and Multi-wavelength Flares
Shigeo S. Kimura, Kenji Toma, Hirofumi Noda +1
Supermassive black holes in active galactic nuclei launch relativistic jets, as indicated by observed superluminal radio blobs. The energy source of these jets is widely discussed…
Can stellar-mass black hole growth disrupt disks of active galactic nuclei? The role of mechanical feedback
Hiromichi Tagawa, Shigeo S. Kimura, Zoltán Haiman +3
Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nuclei (AGN) disks due to gravitational drag and in-situ star formation. However, we find that due to a high…
Evolution of an Accretion Disk in Binary Black Hole Systems
Shigeo S. Kimura, Sanemichi Z. Takahashi, Kenji Toma
We investigate evolution of an accretion disc in binary black hole (BBH) systems and possible electromagnetic counterparts of the gravitational waves from mergers of BBHs. Perna et…
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…
