Discerning the -ray emitting region in the flat spectrum radio quasars
Y. G. Zheng, C. Y. Yang, L. Zhang +1
A model-dependent method is proposed to determine the location of the -ray emitting region for a given flat spectrum radio quasar (FSRQ). In the model, the extra-relativistic el…
Revisiting the structure and spectrum of the magnetic-reconnection-heated corona in luminous AGNs
J. Y. Liu, ErLin Qiao, B. F. Liu
It is believed that the hard X-ray emission in the luminous active galactic nuclei (AGNs) is from the hot corona above the cool accretion disk. However, the formation of the corona…

We present a multi-wavelength study of the unidentified Fermi object, 3FGL J0212.1+5320. Within the 95% error ellipse, Chandra detects a bright X-ray source (i.e., F(0.5-7keV) = 1.…
Dependence of the broad Fe K line on the physical parameters of AGN
Zhu Liu, Weimin Yuan, Youjun Lu +3
In this paper, the dependence of the broad Fe K line on the physical parameters of AGN, such as the black hole mass , accretion rate (equivalently represented by Eddingt…
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…
Curvature of the spectral energy distribution, the dominant process for inverse Compton component and other jet properties in Fermi 2LAC blazars
R. Xue, D. Luo, L. M. Du +7
We fit the spectral energy distributions (SEDs) of members of a large sample of Fermi 2LAC blazars to synchrotron and inverse Compton (IC) models. Our main results are as follows.…
Testing one-zone synchrotron-self-Compton models with spectral energy distributions of Mrk 421
Qianqian Zhu, Dahai Yan, Pengfei Zhang +3
We test one-zone synchrotron self-Compton (SSC) models with high-quality multiwavelength spectral energy distribution (SED) data of Mrk 421. We use Markov chain Monte Carlo (MCMC)…
Search for gamma-ray emission from AE Aquarii with seven years of FERMI-LAT observations
Jian Li, Diego F. Torres, Nanda Rea +4
AE Aquarii (AE Aqr) is a cataclysmic binary hosting one of the fastest rotating (P = 33.08 s) white dwarfs known. Based on seven years of Fermi Large Area Telescope (L…
Effect of spectral index distribution on estimating the AGN radio luminosity function
Zunli Yuan, Jiancheng wang, Ming Zhou +1
In this paper, we scrutinize the effect of spectral index distribution on estimating the AGN (active galactic nucleus) radio luminosity function (RLF) by a Monte Carlo method. We f…
Optical Spectroscopy of Four Young Radio Sources
Xu-Liang Fan, Jin-Ming Bai, Chen Hu +1
We report the optical spectroscopy of four young radio sources which are observed with the Lijiang 2.4m telescope. The Eddington ratios of these sources are similar with those of n…
Modelling the multi-wavelength emission of flat spectrum radio quasar 3C 279
Y. G. Zheng, C. Y. Yang
We employ a length-dependent conical jet model for the jet structure and emission properties of flat spectrum radio quasar 3C 279 in the steady state. In the model, ultra-relativis…
What determines the observational differences of blazars?
Xu-Liang Fan, Jin-Ming Bai, Jirong Mao
We examine the scenario that the Doppler factor determines the observational differences of blazars in this paper. Significantly negative correlations are found between the observa…
Bethe-Heitler cascades as a plausible origin of hard spectra in distant TeV blazars
Y. G. Zheng, C. Y. Yang, S. J. Kang
Context. Very high-energy (VHE) -ray measurements of distant TeV blazars can be nicely explained by TeV spectra induced by ultra high-energy cosmic rays. Aims. We develop a mode…
Twist-induced Magnetosphere Reconfiguration for Intermittent Pulsars
Lei Huang, Cong Yu, Hao Tong
We propose that the magnetosphere reconfiguration induced by magnetic twists in the closed field line region can account for the mode-switching of intermittent pulsars. We carefull…
