Hunting for the candidates of Changing-Look Blazar using Mclust Clustering Analysis
Shi-Ju Kang, Shan-Shan Ren, Yong-Gang Zheng +1
The changing-look blazars (CLBs) are the blazars that their optical spectral lines at different epochs show a significant changes and present a clear transition between the standar…
The changing-look AGN SDSS J101152.98+544206.4 is returning to a type I state
Bing Lyu, Xue-Bing Wu, Yuxuan Pang +11
Aims. We reported the discovery that a changing-look AGN SDSS J101152.98+544206.4 (J1011+5442 for short) gradually returns to the type 1 state after a short period between 2014 and…
On the origin of GeV spectral break for Fermi blazars: 3C 454.3
Shi-Ju Kang, Yong-Gang Zheng, Qingwen Wu +2
The GeV break in spectra of the blazar 3C 454.3 is a special observation feature that has been discovered by the {\it Fermi}-LAT. The origin of the GeV break in the spectra is stil…
An Explanation for 13 consecutive days activities of Mrk 421
Y. G. Zheng, C. Y. Yang, Shi-Ju Kang +1
It is surprising to find a fact for migration in the peak positions of synchrotron spectra energy distribution component during in the activity epochs of Mrk 421, accompanying with…
An empirical "high-confidence" candidate zone for BL Lacertae objects
Shi-Ju Kang, Kerui Zhu, Jianchao Feng +6
In the third catalog of active galactic nuclei detected by the Large Area Telescope Clean (3LAC) sample, there are 402 blazars candidates of uncertain type (BCU). The propo…
Searching for AGN and Pulsar Candidates in 4FGL Unassociated Sources Using Machine Learning
Kerui Zhu, Shi-Ju Kang, Yong-Gang Zheng
In the fourth \emph{Fermi} Large Area Telescope source catalog (4FGL), 5064 -ray sources are reported, including 3207 active galactic nuclei (AGNs), 239 pulsars, 1336 unassociat…
