Variability and Spectral Behavior of Gamma-ray Flares of 3C 279
Gege Wang, Junhui Fan, Hubing Xiao +1
3C 279 showed enhanced flux variations in Fermi-LAT γ-ray observations from January to June 2018. We present a detailed Fermi-LAT analysis to investigate the variability and spectr…
The Classification of Blazars Candidates of Uncertain Types
Jun-Hui Fan, Ke-Yin Chen, Hu-Bing Xiao +6
In this work, the support vector machine (SVM) method is adopted to separate BL Lacertae objects (BL Lacs) and flat spectrum radio quasars (FSRQs) in the plots of photon spectrum i…
An extensive study of blazar broad emission line: Changing-look blazars and Baldwin effect
Hubing Xiao, Junhui Fan, Zhihao Ouyang +4
It is known that the blazar jet emissions are dominated by non-thermal radiation while the accretion disk jets are normally dominated by thermal emission. In this work, our aim is…
The 2175 Å~ Bump Features in FeLoBAL Quasars: One Indicator of MW-like Dust in the Nuclear Region of Quasar
Shaohua Zhang, Jian Ge, Tuo Ji +8
To investigate the properties of dust in the nuclear region of quasars, we explored the extinction curves of the iron low-ionization broad absorption line (FeLoBAL) quasar SDSS J16…
The radio dichotomy of active galactic nuclei
Hubing Xiao, Jingtian Zhu, Liping Fu +2
The question of radio dichotomy in the active galactic nuclei (AGNs) is still in debate even it has been proposed for more than forty years. In order to solve the old riddle, we co…
