Magnetohydrodynamic numerical simulation of the outflows driven by magnetic field and radiation force from the corona above a thin disk
Xiao-Hong Yang, De-Fu Bu, Qi-Xiu Li
A hot corona is suggested to be above the standard thin disk. The anisotropy of hard X-ray emission in radio-quiet active galactic nuclei implies that the corona is not static and…
Active galactic nuclei feedback at parsec scale
De-Fu Bu, Xiao-Hong Yang
We perform simulations to study the effects of active galactic nuclei (AGNs) radiation and wind feedback on the properties of slowly rotating accretion flow at parsec scale. We fin…
Hot accretion flow around neutron stars
De-Fu Bu, Er-Lin Qiao, Xiao-Hong Yang
We perform as the first time hydrodynamic simulations to study the properties of hot accretion flow (HAF) around a neutron star (NS). The energy carried by the HAF will eventually…
What is the real accretion rate onto a black hole for low angular momentum accretion?
De-Fu Bu, Xiao-Hong Yang
Mass accretion rate is a key parameter in accretion disk theory. It determines black hole accretion mode. In large scale cosmological simulations studying galaxy formation and evol…
Quenching black hole accretion by active galactic nuclei feedback
De-Fu Bu, Xiao-Hong Yang
Observations of many dim galactic nuclei in local universe give good estimation of gas density and temperature at Bondi radius. If we assume the black hole accretes at Bondi accret…
