Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 via $χ^{2}$ 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…

Fermi-LAT View on Three Ultra-high-energy 1LHAASO Sources in the $5 2^{\circ} < l < 5 5^{\circ}$ Region

Linjie Liu, Xian Hou, Pierrick Martin +1

Using more than 17 yr of Fermi-LAT data, we performed a detailed investigation of the complex $5 2^{\circ} < l < 5 5^{\circ}$ region, which encompasses the three ultra-high-energy source…
