摘要
The Cygnus Cocoon region is a complex region that contains an OB star cluster that is prominent in the TeV energy range.First observed by HEGRA as the unassociated TeV source TeV J2032+4130, follow-up observations with the High-Altitude Water Cherenkov (HAWC) observatory revealed additional complexity in the region.Previous work has found two sources: 3HWC J2031+415 and 3HWC J2020+403.3HWC J2031+415 is a significant TeV gamma-ray source whose emission is a composition of 2 sources: HAWC J2030+409, associated with the Fermi-LAT Cocoon and HAWC J2031+415, a pulsar wind nebula (PWN) possibly associated with PSR J2032+4127.3HWC J2020+403 is a single source and is associated with the supernova remnant Gamma Cygni.Using a multi-source fitting algorithm in The Multi-Mission Maximum Likelihood framework, an investigation of the TeV spectrum and very-high-energy morphology of HAWC J2031+415 is presented in this work.Additionally, X-ray observations from Suzaku are used to constrain the leptonic production of gamma rays by the PWN.
