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…
Estimating black hole masses in young radio sources using CFHT spectroscopy
Minfeng Gu, Soojong Pak, Luis C. Ho
The correlation between black hole masses and stellar velocity dispersions provides an efficient method to determine the masses of black holes in active galaxies. We obtained optic…
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…
A test on external Compton models for -ray active galactic nuclei
Zhonghui Fan, Xinwu Cao, Minfeng Gu
There is clear evidence that the -ray emission from active galactic nuclei (AGNs) is attributed to the inverse Compton scatterings in the relativistic blobs near the massive bla…
