Abstract content <br> &nbsp; (Max 300 words)

Electrons and positrons escape from the pulsar in the form of a relativistic wind. These particles undergo synchrotron radiation as well inverse Compton collisions with photons from the Cosmic Microwave Background Radiation, leading to measurable non-thermal emission. The purpose of this project is to test a first order approximation model that calculates changes in the lepton spectrum due to the radiation processes, as well as the subsequent non-thermal emission. The model makes use of several parameters which we vary in an attempt to fit a observed photon spectrum from a source with known parameters. We find the model to have a moderate success as a first order approximation and apply it to a number of unknown sources.
