Evaluating the classification of Fermi BCUs from the 4FGL Catalog Using Machine Learning
Shi-Ju Kang, Enze Li, Wujing Ou +4
The recently published fourth Fermi Large Area Telescope source catalog (4FGL) reports 5065 gamma-ray sources in terms of direct observational gamma-ray properties. Among the sourc…
The relationship between the radio core-dominance parameter and spectral index in different classes of extragalactic radio sources (III)
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +3
Active galactic nuclei (AGNs) can be divided into two major classes, namely radio-loud and radio-quiet AGNs. A small subset of the radio-loud AGNs is called blazars, which are beli…
Radio core dominance of Fermi-LAT selected AGNs
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +2
Aims. We present a sample of 4388 AGNs with available radio core-dominance parameters defined as the ratio of the core flux densities to extended ones, namely, R = Score/Sext., whi…
Correlation Analysis for Gamma-ray (radio) and Broad Line Emissions of Fermi Blazars
Lixia Zhang, Junhui Fan, Yuhai Yuan
In this work, we compiled a sample of 202 Fermi/LAT blazars with available broad line emissions. Out of the 202 sources, 66 have known Doppler factors. The correlation between (…
Evaluating the optical classification of Fermi BCUs using machine learning
Shi-Ju Kang, Junhui Fan, Weiming Mao +3
In the third catalog of active galactic nuclei detected by the Fermi-LAT (3LAC) Clean Sample, there are 402 blazars candidates of uncertain type (BCU). Due to the limitations of as…
Comparison between Detected and non- Detected Superluminal Sources
Hubing Xiao, Junhui Fan, Jianghe Yang +8
Active galactic nuclei (AGNs) have been attracting research attention due to their special observable properties. Specifically, a majority of AGNs are detected by Fermi-LAT mission…
