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…
A Radio Changing-state Jet in the Narrow-line Seyfert 1 Galaxy J1105+1452
Liming Dou, Zhining Chen, Jiahua Wu +9
We report the discovery of a radio-quiet to radio-loud transition in the narrow-line Seyfert 1 galaxy J1105+1452. The source has undergone a long-term evolution from a radio-quiet…
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…
Modeling the Multiwavelength Emission of 3C 279 during the 14 years of Fermi-LAT Era
Krishna Mohana A, Alok C. Gupta, Junhui Fan +7
We report the results of our long-term multiwavelength spectral energy distribution (SED) study on the flat spectrum radio quasar 3C 279 during the years (2008--2022) of {…
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…
The Study of Jet Formation Mechanism in Fermi Blazars
Shangchun Xie, Zhihao Ouyang, Jingyu Wu +5
The origin of jet launching mainly comes from two mechanisms: the BZ mechanism and the BP mechanism. However, it is in debate which one is dominating in blazars. In this work, we u…
The particle acceleration study in blazar jet
Hubing Xiao, Wenxin Yang, Yutao Zhang +4
The particle acceleration of blazar jets is crucial to high-energy astrophysics, yet the acceleration mechanism division in blazar subclasses and the underlying nature of these mec…
Identification of 4FGL uncertain sources at Higher Resolutions with Inverse Discrete Wavelet Transform
Haitao Cao, Hubing Xiao, Zhijian Luo +2
In the forthcoming era of big astronomical data, it is a burden to find out target sources from ground-based and space-based telescopes. Although Machine Learning (ML) methods have…
