Joint Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 Using Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +8
We propose a joint multi-epoch profile-likelihood analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk 42…

Formation of the Electronic Spectrum in Relativistic Jets of Gamma-Ray Blazars
Y. G. Zheng, G. B. Long, C. Y. Yang +1
We describe the theory of Fermi-type acceleration, including first-order Fermi acceleration at a parallel shock front and second-order Fermi acceleration in a test particle limit.…

Verification of the diffusive shock acceleration in Mrk 501
Y. G. Zheng, G. B. Long, C. Y. Yang +1
The present work considers a plane shock front propagating along a cylindrical jet. Electrons experience the diffusive shock acceleration around the shock front, and subsequently d…
