Description
Recently, the Large High Altitude Air Shower Observatory (LHAASO) reported discovery of 12 ultrahigh-energy (UHE; ε > 100 TeV) gamma-ray sources located in the Galactic plane. We have used the multiwavelength radiation from these sources by considering a PWN origin, where the emission is powered by time-dependent spin-down luminosity of the associated pulsars. In this time-dependent leptonic emission
model, the electron population is calculated at different times under the radiative (synchrotron and inverse-Compton) and adiabatic cooling. The escape of particles from these PWN has been studied and their effects on the model parameters is estimated.
