Observational Evidence for Young Radio Galaxies are Triggered by Accretion Disk Instability
Qingwen Wu
The bolometric luminosities and black hole (BH) masses are estimated by various methods for a sample of young radio galaxies with known ages. We find that the ages are positively c…
On the BL Lacertae objects/radio quasars and the FRI/II dichotomy
Ya-Di Xu, Xinwu Cao, Qingwen Wu
In the frame of unification schemes for radio-loud active galactic nuclei (AGNs), FR I radio galaxies are believed to be BL Lacertae (BL Lac) objects with the relativistic jet misa…
The Hard X-ray Spectral Evolution in XRBs, AGNs and ULXs
Qingwen Wu, Minfeng Gu
We explore the relationship between the hard X-ray photon index and the Eddington ratio (ξ=L_{X}(0.5-25 keV)/L_{Edd}) in six XRBs. We find that different XRBs follow different…
Jet power extracted from ADAF and the applications to X-ray binaries and radio galaxy FR dichotomy
Qingwen Wu, Xinwu Cao
We calculate the jet power of the classical Blandford-Znajek(BZ) model and hybrid model developed by Meier based on the global solutions of advection dominated accretion flows (ADA…
The hard X-ray spectral evolution in X-ray binaries and its application to constrain the black hole mass of ultraluminous X-ray sources
Qingwen Wu, Minfeng Gu
We investigate the relationship between the hard X-ray photon index and the Eddington ratio () in six X-ray binaries (XRBs) with well constrain…
On the origin of X-ray emission in some FR Is: ADAF or jet?
Qingwen Wu, Feng Yuan, Xinwu Cao
We investigate the X-ray origin in FR Is using the radio, submillimetre, optical, and {\em Chandra} X-ray data of a small sample consisting of eight FR I sources. These sources are…
