Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 via Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
We present a joint multi-period analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk~421. Photon-ALP osci…
A Concept of Next-Generation Atmospheric Cherenkov Telescope Array (NG-ACTA)
Jiancheng Wang, Jirong Mao
The Next-Generation Atmospheric Cherenkov Telescope Array (NG-ACTA) is proposed as a prospective infrastructure for very high energy (VHE) gamma-ray astronomy, consisting of a mixe…
CosmicWeb-21cm array: A New Radio Observation Array Design for 21cm Cosmology
Jiancheng Wang, Jirong Mao, Xiangming Cheng +10
This paper presents the CosmicWeb-21cm array, a novel radio interferometer designed to overcome the key challenges in 21 cm cosmology. Its core innovations include: (1) a multi-sca…
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,…
Revisiting Very High Energy Gamma-Ray Absorption in Cosmic Propagation under the Combined Effects of Axion-Like Particles and Lorentz Invariance Violation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
Very-high-energy (VHE; GeV) gamma rays are expected to experience strong attenuation during cosmological propagation due to electron-positron pair production on the…
Studies of Extragalactic Background Light with TeV BL Lac Objects
Longhua Qin, Jiancheng Wang, Quangui Gao +4
Very high energy (VHE; 100GeV) ray from cosmological distances are attenuated by the extragalactic background light (EBL) in the IR to UV band. By contrasting measured…
Discerning the -ray emitting region in the flat spectrum radio quasars
Y. G. Zheng, C. Y. Yang, L. Zhang +1
A model-dependent method is proposed to determine the location of the -ray emitting region for a given flat spectrum radio quasar (FSRQ). In the model, the extra-relativistic el…
