Detection of a possible high-confidence radio quasi-periodic oscillation in the BL Lac PKS J2134-0153
Guowei Ren, Nan Ding, Xiong Zhang +5
We have searched quasi-periodic oscillations (QPOs) for BL Lac PKS J2134-0153 in the 15 GHz radio light curve announced by the Owens Valley Radio Observatory 40-m telescope during…
Detection of a high-confidence quasi-periodic oscillation in radio light curve of the high redshift FSRQ PKS J0805-0111
Guo-Wei Ren, Hao-Jing Zhang, Xiong Zhang +5
In this work, we have searched quasi-periodic oscillations (QPOs) in the 15 GHz light curve of the FSRQ PKS J0805-0111 monitored by the Owens Valley Radio Observatory (OVRO) 40 m t…
Multi-color optical monitoring of the quasar 3C 273 from 2005 to 2016
Dingrong Xiong, Jinming Bai, Haojing Zhang +4
We have monitored the quasar 3C 273 in optical , and bands from 2005 to 2016. Intraday variability (IDV) is detected on seven nights. The variability amplitudes for most…
The physical properties of \textit{Fermi} TeV BL Lac objects jets
N. Ding, X. Zhang, D. R. Xiong +1
We investigate the physical properties of \textit{Fermi} TeV BL Lac objects jets by modeling the quasi-simultaneous spectral energy distribution of 29 \textit{Fermi} TeV BL Lacs in…
Multi-color optical monitoring of Mrk 501 from 2010 to 2015
Dingrong Xiong, Xiong Zhang, Tingfeng Yi +5
We have monitored the BL Lac object Mrk 501 in optical , and bands from 2010 to 2015. For Mrk 501, the presence of strong host galaxy component can affect the results of…
The beaming effect and -ray emission for Fermi blazars
Yong-Yun Chen, Xiong Zhang, Dingrong Xiong +2
We study the -ray luminosity and beaming effect for Fermi blazars. Our results are as follows. (i) There are significant correlations between -ray luminosity and radio…
From the "blazar sequence" to unification of blazars and radio galaxies
Dingrong Xiong, Xiong Zhang, Jinming Bai +1
Based on a large Fermi blazar sample, the blazar sequence (synchrotron peak frequency versus synchrotron peak luminosity ) is revisited. It is found th…
Jet/accretion and Unification for FSRQs/FRII and BL Lac objects/FRI radio galaxies
Yongyun Chen, Xiong Zhang, Haojing Zhang +5
We compiled a sample of 24 flat-spectrum radio quasars (FSRQs), 21 BL Lacs, 13 FRI and 12 FRII radio galaxies to study the jet power and broad-line luminosity relation, and the jet…
The jets-accretion relation, mass-luminosity relation in Fermi blazars
Xiaoling Yu, Xiong Zhang, Haojing Zhang +6
A sample of 111 Fermi blazars each with a well-established radio core luminosity, broad-line luminosity, bolometric luminosity and black hole mass has been compiled from the litera…
Black hole mass, jet power and accretion in AGN
Yong-Yun Chen, Xiong Zhang, Dingrong Xiong +1
We study the relation between accretion, black hole mass and jet power in AGN, by using a large group of blazars detected by the Fermi Large Area Telescope and radio galaxies. Our…
Basic properties of Fermi blazars and the "blazar sequence"
Dingrong Xiong, Xiong Zhang, Jinming Bai +1
By statistically analyzing a large sample which includes blazars of Fermi detection (FBs) and non-Fermi detection (NFBs), we find that there are significant differences between FBs…
Core-dominance parameter, black hole mass and jet-disc connection in Fermi blazars
Y. Y. Chen, X. Zhang, H. J. Zhang +1
We study the relationship between jet power and accretion for Fermi and non-Fermi blazars, respectively. We also compare the relevant parameter between them. Our main results are a…
Intrinsic -ray luminosity, black hole mass, jet and accretion in Fermi blazars
Dingrong Xiong, Xiong Zhang
We have analyzed a large sample of clean blazars detected by Fermi Large Area Telescope (LAT). Using literature and calculation, we obtained intrinsic -ray luminosity excluding…
