Energy-Dependent Shifts of Medium-Scale Anisotropies in Very-High-Energy Cosmic Rays Observed by LHAASO-KM2A
The LHAASO collabration, Zhen Cao, F. Aharonian +310
Small deviations from isotropy in the arrival directions of Galactic cosmic rays serve as a unique probe of the local magnetic environment. In this Letter, we report observations o…
Energy calibration of LHAASO-KM2A using the cosmic ray Moon shadow
Zhen Cao, F. Aharonian, Y. X. Bai +323
We present a precise measurement of the westward, rigidity-dependent shift of the Moon's shadow using three and a half years of cosmic-ray data collected by the Kilometer Square Ar…
Precise measurements of the cosmic ray proton energy spectrum in the "knee'' region
The LHAASO Collaboration, Zhen Cao, F. Aharonian +310
We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower…
Ultra-high-energy -ray emission associated with the tail of a bow-shock pulsar wind nebula
Zhen Cao, F. Aharonian, Y. X. Bai +292
In this study, we present a comprehensive analysis of an unidentified point-like ultra-high-energy (UHE) -ray source, designated as 1LHAASO J1740+0948u, situated in the vicinity…
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…
