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…
Optical flux and spectral variability of BL Lacertae during its historical high outburst in 2020
Nibedita Kalita, Yuhai Yuan, Minfeng Gu +9
BL Lacertae had undergone a series of historical high flux activity over a year, from August 2020 in the optical to VHE -rays. In this paper, we report on optical flux and spect…
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…
Constraining the -ray Emission Region for Fermi-Detected FSRQs by the Seed Photon Approach
Danyi Huang, Ziyan Li, Jiru Liao +5
The location of -ray emitting region in blazars has been an open issue for several decades and is still being debated. We use the Paliya et al. sample of 619 -ray-loud flat-s…
A Possible 3-Year Quasi-Periodic Oscillation in γ-Ray Emission from the FSRQ S5 1044+71
G. G. Wang, J. T. Cai, J. H. Fan
Variability is a typical observation feature of Fermi blazars, sometimes it shows quasi-periodic oscillation (QPO). In this work, we obtained 5-day binned light curves (with a time…
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…
