A Helical Trajectory Interpretation of a Multi-wavelength Event in a Blazar S5 0716+714
Zhihao Ouyang, Jingyu Wu, Hubing Xiao +9
Relativistic jets in blazars exhibit strong variability across multiple timescales, but the connection between temporal variability and the evolution of jet structures remains poor…
Exceptional Gamma-Ray Flaring Activity of the Blazar S4 0954+65 in Early 2025
Zhihao Ouyang, Jingyu Wu, Hubing Xiao +11
S4 0954+65 (4FGL J0958.7+6534) is a TeV-detected blazar at a redshift of , classified as an intermediate-synchrotron-peaked BL Lac object. In early 2025, it…
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…
Detection of Quasi-periodic Oscillations in the -Ray Light Curve of 4FGL J0309.9-6058
Jingyu Wu, Zhihao Ouyang, Hubing Xiao +7
In this work, we report, for the first time, a quasi-periodic oscillation (QPO) in the -ray band of 4FGL J0309.9-6058, also known as PKS 0308-611. We employed three analytical m…
The averaged broadband spectral energy distribution study of Fermi bright BL Lac objects
Hubing Xiao, Haitao Cao, Rui Xue +6
The physics-determined broadband spectral energy distributions (SEDs) of blazars have been widely used to study the property during their flaring/outburst states, while the non-fla…
Revisiting the flaring activity in early 2015 of BL Lacertae object S5 0716+714
Zhihao Ouyang, Hubing Xiao, Marina Manganaro +7
In this work, we analyzed multi-wavelength data of the BL Lac object S5 0716+714 to investigate its emission mechanisms during a flaring state observed in early 2015. We examined t…
