The advection-dominated accretion flow+thin accretion disk model for two low-luminosity active galactic nuclei: M81 and NGC4579
Ya-Di Xu, Xinwu Cao
It was found that the advection-dominated accretion flow (ADAF)+thin disk model calculations can reproduce the observed spectral energy distributions (SED) of the two low luminosit…
Thermal X-Ray Iron Line Emission from the Galactic Center Black Hole Sagittarius A*
Ya-Di Xu, Ramesh Narayan, Eliot Quataert +2
We model thermal X-ray emission from the accreting supermassive black hole Sagittarius A* at the Galactic Center. For the region inside of the center, we use a…
Constraints on radiatively inefficient accretion history from Eddington ratio distribution of active galactic nuclei
Xinwu Cao, Ya-Di Xu
The transition of a standard thin disk to a radiatively inefficient accretion flow (RIAF) is expected to occur, when the accretion rate is close to the critical rate. The radiative…
The radiation properties of an accretion disk with a non-zero torque on its inner edge
Xinwu Cao, Y. D. Xu
The structure of the inner edge of the accretion disk around a black hole can be altered, if the matter inside the marginally stable orbit is magnetically connected to the disk. In…
