Indication of Another Intermediate-mass Black Hole in the Galactic Center
Shunya Takekawa, Tomoharu Oka, Yuhei Iwata +2
We report the discovery of molecular gas streams orbiting around an invisible massive object in the central region of our Galaxy, based on the high-resolution molecular line observ…
Line-driven disc wind in near-Eddington active galactic nuclei: decrease of mass accretion rate due to powerful outflow
Mariko Nomura, Ken Ohsuga, Chris Done
Based on recent X-ray observations, ultra-fast outflows from supermassive black holes are expected to have enough energy to dramatically affect their host galaxy but their launch a…
Magnetohydrodynamic Simulations of a Plunging Black Hole into a Molecular Cloud
Mariko Nomura, Tomoharu Oka, Masaya Yamada +4
Using two-dimensional magnetohydrodynamic simulations, we investigated the gas dynamics around a black hole plunging into a molecular cloud. In these calculations, we assumed a par…
