Description

We present an analysis of the source 1LHAASO J2028+3352 reported in the 1LHAASO catalog. The source is spatially coincident with the pulsar PSR J2028+3332, which has a characteristic age of 580 kyr. Based on the LHAASO data, our fitting results reveal that the source exhibits a large extension and an elliptical spatial morphology. These observational characteristics support the source as a candidate of pulsar halo.
