From the Fermi blazar sequence to the relation between Fermi blazars and gamma-ray Narrow-line Seyfert 1 Galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +6
We use the third catalog of blazars detected by Fermi/LAT (3LAC) and gamma-ray Narrow-line Seyfert 1 Galaxies (gamma-NLSy1s) to study the blazar sequence and relationship between t…
Beamed and unbeamed emission of -ray blazars
Zhiyuan Pei, Junhui Fan, Jianghe Yang +1
A two-component model of radio emission has been used to explain some radio observational properties of Active Galactic Nuclei (AGNs) and, in particular, of blazars. In this work,…
The estimation of -ray Doppler factor for Fermi/LAT-detected blazars
Zhiyuan Pei, Junhui Fan, Jianghe Yang +1
Blazars are a subclass of active galactic nuclei (AGNs) with extreme observation properties, which is caused by the beaming effect, expressed by a Doppler factor, in a relativistic…
Revisiting the Relationship between the Long GRB Rate and Cosmic Star Formation History Based on a Large Swift Sample
Jing-Meng Hao, Liang Cao, You-Jun Lu +4
The exact relationship between the long gamma-ray burst (LGRB) rate and the cosmic star formation rate (CSFR) is essential for using LGRBs as cosmological probes. In this work, we…
Efficient Fermi Source Identification with Machine Learning Methods
Hubing Xiao, Haitao Cao, Junhui Fan +3
In this work, Machine Learning (ML) methods are used to efficiently identify the unassociated sources and the Blazar Candidate of Uncertain types (BCUs) in the Fermi-LAT Third Sour…
Further evidences of superluminal AGNs as -ray sources
Hubing Xiao, Junhui Fan, Riccardo Rando +2
In our previous work in Xiao et al. (2019), we suggested that 6 superluminal sources could be gamma-ray candidates, and in fact 5 of them have been confirmed in the fourth Fermi-LA…
