Abstract
The HAWC gamma-ray observatory has detected very high energy gamma-ray emission from numerous PWNe. The radiation originates from pulsar driven winds accelerating electrons and positrons, which propagate into the local medium and up-scatter photons. Notable among the HAWC detections are Geminga and PSR B0659+1414, which exhibit large extended, low energy density ‘halos’ reaching 10s of pc away from the central source. In this analysis, we seek to understand if these halos are a ubiquitous feature, or depend on the specific environments or other characteristics of the pulsars. Using the Geminga pulsar halo as a template and the ATNF catalog as a target list, we performed a systematic search for TeV emission from known young and middle-aged pulsars. By assuming Geminga-like features, if a pulsar's distance and spin-down power are known, we can predict both the flux and extent and compare it to the measurements by HAWC.
