Search for Ultra-Relativistic Magnetic Monopoles with LHAASO-KM2A

Zhen Cao, F. Aharonian, Y. X. Bai +335

Ultra-relativistic magnetic monopoles traversing the atmosphere are expected to initiate extensive air showers characterized by a muon deficit and a compact lateral profile. Using…

Constraining the Cosmic-ray Energy Based on Observations of Nearby Galaxy Clusters by LHAASO

The LHAASO Collaboration, Zhen Cao, F. Aharonian +323

Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse -rays detectable by arrays such as LH…
