Description
TeV Halos are regions of extended emission around pulsars, produced due to inverse-Compton scattering of photons by particles accelerated inside and diffused away from the pulsar wind nebulae. TeV Halos, discovered in 2017 by the HAWC Collaboration, represent a possible detection tool for “silent” pulsars, those whose radiation jets are never oriented towards Earth. In addition, TeV Halos are very energetic cosmic accelerators and represent an uncharacterized population of gamma-ray sources that contribute to the galactic and extragalactic diffuse gamma-ray background. Finally, given their high-energy emission, these halos are potential probes for the search for Dark Matter. Thus, improvement of techniques to search for Halos is very important. In this work, we present a simulation of the gamma-ray emission of Geminga and Monogem side-by-side with the observations by HAWC. We use a simplified model for the emission based on pulsar characteristics. This project was supported by DGAPA PAPIIT IG101320.
