SDSS spectroscopy for blazars in the LAT bright AGN sample
Zhaoyu Chen, Minfeng Gu, Zhonghui Fan +1
We have collected all available spectra and photometric data from SDSS catalogue for bright AGNs complied from the first three months of the Fermi large area telescope all-sky surv…
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…
VLBI observations of seven BL Lac objects from RGB sample
Zhongzu Wu, D. R. Jiang, Minfeng Gu +1
We present EVN observations of seven BL Lac objects selected from the RGB sample. To investigate the intrinsic radiation property of BL Lac objects, we estimated the Doppler factor…
Multi-colour optical monitoring of eight red blazars
Minfeng Gu, C. -U. Lee, Soojong Pak +2
We present the observational results of multi-colour optical monitoring of eight red blazars from 2003 September to 2004 February. The aim of our monitoring is to investigate the s…
The jet power, radio loudness and black hole mass in radio loud AGNs
Yi Liu, Dong Rong Jiang, Min Feng Gu
The jet formation is thought to be closely connected with the mass of central supermassive black hole in Active Galactic Nuclei. The radio luminosity commonly used in investigating…
