Description
Extended TeV sources associated with pulsars can be divide into two categories: pulsar wind nebula with TeV emission originating in the zone dominated by the pulsar; TeV halo with escaped particle diffusing into the ISM. The First LHAASO Catalog of Gamma-ray Sources found 35 sources with pulsar association. Based on it, we unveil the correlation between LHAASO sources and associated pulsars by spectral and morphological analysis. The observed properties of a PWN/TeV halo can be used to constrain the physical characteristics of the pulsar and surrounding environment. The spectral evolution of PWN/TeV halo shows that peak energy increase with pulsar age. Nebula and halo are explained in a unified scheme.
