Antarctic TianMu Staring Observation Project I: Overview and Implementation of the Prototype Telescope
Dan Zhou, Jing Zhong, Jianchun Shi +31
Wide-field rapid sky surveys serve as critical observational methods for time-domain astronomical research. The Antarctic region, with several months of continuous dark nights annu…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes…
Pattern and Origin for the Extreme -ray Flares of 3C 454.3 and 3C 279: An Astrophysical Critical Damper?
Haiyun Zhang, Dahai Yan, Jianeng Zhou +2
We apply a Gaussian process method to the extreme -ray flares of 3C 454.3 and 3C 279 to discover the variable patterns and then to investigate the physical origins of the giant…
Detection of the cosmological evolution of the Doppler factor for blazars jets
Dahai Yan, Haiyun Zhang, Jianeng Zhou +1
The Doppler factor () is a fundamental quality for the relativistic jets from active galactic nuclei (AGNs). It is also fundamental to assessing the number of the entire popula…
