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…
