Rapid Variability and Broadband Spectral Modeling in the Flaring Activity of BL Lacertae
Xin Chang, Dingrong Xiong, Chenxu Liu +17
We report a multi-wavelength study of two flaring episodes of the blazar BL Lacertae during MJD 60500-60800 (9 July 2024 - 5 May 2025). The source reached a daily-averaged -ray…
PKS 2254+074: A Blazar in Likely Association with the Neutrino Event IceCube-190619A
Shunhao Ji, Zhongxiang Wang
We report our study of the field of a 0.2 PeV neutrino event IC-190619A. This neutrino belongs to Gold events, which more likely have an astrophysical origin. Among the two…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
Fermi Blazars in the Zwicky Transient Facility Survey: Properties of Large Optical Variations
Si-Si Sun, Zhongxiang Wang, Shun-hao Ji
We analyze the optical light-curve data, obtained with the Zwicky Transient Facility (ZTF) survey, for 47 gamma-ray blazars monitored by the Large Area Telescope onboard {\it the F…
Identifying Three New AGNs Among Fermi Unidentified Gigaelectronvolt Sources
Shunhao Ji, Zhongxiang Wang, Qiangmeng Huang +1
We report our identification of three gigaelectronvolt -ray sources, 4FGL J0502.6+0036, 4FGL J1055.9+6507, and 4FGL J1708.2+5519, as Active Galactic Nuclei (AGNs). They are list…
