Description
Charged cosmic rays (CRs) are believed to propagate diffusively in the turbulent magnetic field of the Milky Way. The diffusion coefficient, which depends on the properties of the turbulent interstellar medium (ISM), is a key parameter governing CR propagation. We present an updated analysis of the extended very-high-energy (VHE) gamma-ray emission around the middle-aged (207.8 kyr) pulsar PSR J0622+3749 using LHAASO data, including the spatial significance (TS), energy spectrum, and constraints on the diffusion coefficient. These results provide new insights into the diffusion process of cosmic rays in the vicinity of the pulsar.
