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…
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…
The relation between star formation rate and accretion rate in LINERs
Qingwen Wu, Xinwu Cao
It is argued that there is a linear correlation between star formation rate (SFR) and accretion rate for normal bright active galactic nuclei (AGNs). However, it is still unclear w…
Origin of Radio Emission from Nearby Low-Luminosity Active Galactic Nuclei
Qingwen Wu, Xinwu Cao
We use the observational data in radio, optical and X-ray wavebands, for a sample of active galactic nuclei (AGNs) with measured black hole masses, to explore the origin of radio e…
