HAWC Observation of Supernova Remnants and Pulsar Wind Nebulae

摘要

The majority of Galactic TeV gamma-ray sources are pulsar wind nebulae (PWNe)and supernova remnants (SNRs), and the most common association for unidentifiedsources is PWN. Many of these sources were discovered in TeV by imaging airCherenkov telescopes using overlapping pointed observations over sections ofthe Galactic plane. The HAWC observatory is a survey type instrument in theNorthern hemisphere with an energy range of 100 GeV to 100 TeV. Preliminaryanalysis of data recorded with the partially completed HAWC array taken since2013 shows extended detections that are coincident with known TeV SNRs andPWNe. The full array became operational in early 2015 and has been steadilysurveying the Northern sky since. I will discuss detections in HAWC data takensince 2013 associated with PWNe and SNRs.
