On the thermal line emission from the outflows in ultraluminous X-ray sources
Ya-Di Xu, Xinwu Cao
The atomic features in the X-ray spectra of the ultraluminous X-ray source (ULX) may be associated with the outflow (Middleton et al. 2015), which may provide a way to explore the…
Anisotropic radiation from accretion disc-coronae in active galactic nuclei
Ya-Di Xu
In the unification scheme of active galactic nuclei (AGN), Seyfert 1s and Seyfert 2s are intrinsically same, but they are viewed at different angles. However, the Fe Kαemission lin…
The relation of optical/UV and X-ray emission in low-luminosity active galactic nuclei
Ya-Di Xu
We study the relation of optical/UV and X-ray emission in the low luminosity active galactic nuclei (LLAGNs), using a sample of 49 sources including 28 local Seyfert galaxies and 2…
Unification of Radio Galaxies and Their Accretion/Jet Properties
Qingwen Wu, Ya-Di Xu, Xinwu Cao
We investigate the relation between black hole mass, M_bh, and jet power, Q_jet, for a sample of BL Lacs and radio quasars. We find that BL Lacs are separated from radio quasars by…
Thermal X-ray iron line emission from the advection dominated accretion flow in the galactic binary GX 339-4
Ya-Di Xu
We explore thermal X-ray iron line emission from the galactic X-ray binary GX 339-4 in the off state, using the models of the advection dominated accretion flow (ADAF) without or w…
Growth of massive black holes at their late stage
Ya-Di Xu, Xinwu Cao
We derive the black hole mass density as a function of redshift with the bolometric luminosity function of AGN assuming that massive black holes grew via accreting the circumnuclea…
