Low density, radiatively inefficient rotating-accretion flow onto a black hole
Kohei Inayoshi, Jeremiah P. Ostriker, Zoltan Haiman +1
We study low-density axisymmetric accretion flows onto black holes (BHs) with two-dimensional hydrodynamical simulations, adopting the -viscosity prescription. When the gas angu…
Rapid growth of black holes accompanied with hot or warm outflows exposed to anisotropic super-Eddington radiation
E. Takeo, K. Inayoshi, K. Ohsuga +2
We perform two-dimensional radiation hydrodynamical simulations of accretion flows onto a black hole (BH) with a mass of in order to s…
Quenching of supermassive black hole growth around the apparent maximum mass
Kohei Ichikawa, Kohei Inayoshi
Recent quasar surveys have revealed that supermassive black holes (SMBHs) rarely exceed a mass of during the entire cosmic hist…
Probing stellar binary black hole formation in galactic nuclei via the imprint of their center of mass acceleration on their gravitational wave signal
Kohei Inayoshi, Nicola Tamanini, Chiara Caprini +1
Multi-frequency gravitational wave (GW) observations are useful probes of the formation processes of coalescing stellar-mass binary black holes (BBHs). We discuss the phase drift i…
Opacity limit for supermassive protostars
Fernando Becerra, Federico Marinacci, Kohei Inayoshi +2
We present a model for the evolution of supermassive protostars from their formation at until their growth to $M_\star \simeq 10^5\,\text{M}_\o…
