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…
Systematic two-dimensional radiation hydrodynamic simulations of super-Eddington accretion flow and outflow: Comparison with the slim disk model
Takaaki Kitaki, Shin Mineshige, Ken Ohsuga +1
To what extent can the one-dimensional slim disk model reproduce the multi-dimensional results of global radiation-hydrodynamic simulations of super-Eddington accretion? With this…
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…
Three-dimensional structure of clumpy outflow from supercritical accretion flow onto black holes
Hiroshi Kobayashi, Ken Ohsuga, Hiroyuki R. Takahashi +4
We perform global three-dimensional (3D) radiation-hydrodynamic (RHD) simulations of out- flow from supercritical accretion flow around a 10 Msun black hole. We only solve the outf…
