The Physical Properties of Changing-look Blazars
Shi-Ju Kang, Bing Lyu, Qingwen Wu +2
Changing-look active galactic nuclei (AGNs) are a special class of AGNs that change their spectral type from type 1 to type 2 or vice versa. In recent years, a number of changing-l…
GeV Variability Properties of TeV Blazars Detected by Fermi-LAT
Gege Wang, Hubing Xiao, Junhui Fan +1
Variability is a prominent observational feature of blazars. The high-energy radiation mechanism of jets has always been important but still unclear. In this work, we performed a d…
Jet power extracted from ADAFs and the application to Fermi BL Lacertae objects
Chen Yongyun, Gu Qiusheng, Fan Junhui +4
We calculate the jet power of the Blandford-Znajek (BZ) model and the hybrid model based on the self-similar solution of advection-dominated accretion flows (ADAFs). We study the f…
Characterizing the emission region property of blazars
Junhui Fan, Hubing Xiao, Wenxin Yang +4
The studies and constraints on the emission region are crucial to the blazar radiation mechanism. Yet the previous works mainly focus on individual sources. In this work, we make u…
Intra-night optical flux and polarization variability of BL~Lacertae during its 2020 2021 high state
Rumen Bachev, Tushar Tripathi, Alok C. Gupta +15
In this work, we report the presence of rapid intra-night optical variations in both -- flux and polarization of the blazar BL Lacertae during its unprecedented 2020--2021 high sta…
The `blazar sequence' in TeV band
Zhihao Ouyang, Hubing Xiao, Jianzhen Chen +7
The `blazar sequence' has been proposed for more than 20 years, yet its nature is still unclear. In this work, for the first time, we expand this topic to the TeV band by using a s…
Jet power, intrinsic -ray luminosity and accretion in jetted AGN
Chen Yonhyun, Gu Qiusheng, Fan Junhui +4
The correlation between the kinetic jet power , intrinsic -ray luminosity () and accretion () may reveal the underlying jet physics in va…
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 jet formation mechanism of Gamma-ray Narrow-line Seyfert 1 Galaxies
Chen Yongyun, Gu Qiusheng, Fan Junhui +4
Under the coronal magnetic field, we estimate the maximal jet power of the Blandford-\Znajek (BZ) mechanism, Blandford-\Payne (BP) mechanism, and hybrid model. The jet power of the…
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…
