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…
