The first TeV gamma-ray source with no lower energy counterparts, TeV J2032+ 4130, was
discovered by HEGRA. It appears in the third HAWC catalog as 3HWC J2031+ 415 and it is
a bright TeV gamma-ray source whose emission has previously been resolved as 2 sources:
HAWC J2031+ 415 and HAWC J2030+ 409. While HAWC J2030+ 409 has since been

The first TeV gamma-ray source with no lower energy counterparts, TeV J2032+4130, was discovered by HEGRA. It appears in the third HAWC catalog as 3HWC J2031+415 and it is a bright TeV gamma-ray source whose emission has previously been resolved as 2 sources: HAWC J2031+415 and HAWC J2030+409. While HAWC J2030+409 has since been associated with the \emph{Fermi-LAT} Cygnus Cocoon, no such association for HAWC J2031+415 has yet been found. In this work, we investigate the spectrum and energy-dependent morphology of HAWC J2031+415. We associate HAWC J2031+415 with the pulsar PSR J2032+4127 and perform a combined multi-wavelength analysis using radio, X-ray, and -ray emission. We conclude that HAWC J2031+415 and, by extension, TeV J2032+4130 are most probably a pulsar wind nebula (PWN) powered by PSR J2032+4127.
