Quasi-Simultaneous Broadband Spectral Energy Distributions of a Sample of Fermi Blazars -- I. Correlation Results
Yi Zhong, Zhujian Wan, Rui Xue +3
Blazars' non-thermal emission shows rapid variability across all wavelengths, so spectral energy distributions (SEDs) built from quasi-simultaneous data are crucial for revealing t…
Chasing the neutrino blazar candidates II: SED modeling with hadronic model
Hubing Xiao, Zhihao Ouyang, Lili Yang +6
Blazars are promising candidates for high energy neutrino sources, yet the physical origin of their neutrino emission remains uncertain. In this work, we extend our previous study…
Changing-look Active Galactic Nuclei from SDSS, LAMOST and DESI Surveys
Guohai Chen, Wenxin Yang, Xuhong Ye +4
Results. We identify 45 CLAGNs, of which 40 are newly reported. The sample is dominated by turn-off events, comprising 43 turn-off and 2 turn-on sources. This may be because Type 2…
Detection of an Orphan X-ray Flare from a Blazar Candidate EP240709a with Einstein Probe
Mingjun Liu, Yijia Zhang, Yun Wang +49
Blazars are often observed to flare across multiple wavelengths. Orphan flares from blazars have been only detected a few times, providing an opportunity to understand the structur…
Understanding the phenomenological and intrinsic blazar sequence using a simple scaling model
Zhu-Jian Wan, Rui Xue, Ze-Rui Wang +2
The blazar sequence, including negative correlations between radiative luminosity and synchrotron peak frequency , and between Compton dominance and , is wi…
