Abstract | This paper investigates the origin of the \(\gamma\)-ray emission from MGRO J1908+06 in the GeV-TeV energy band. By analyzing the data collected by {\it Fermi}-LAT, VERITAS, and HAWC, with the addition of spectral data previously reported by LHAASO, a multiwavelength (MW) study of the morphological and spectral features of MGRO J1908+06 provides insight into the origin of the \(\gamma\)-ray emission. The mechanism behind the bright TeV emission is studied by constraining the magnetic field strength, the source age and the distance through detailed broadband modeling. Both spectral shape and energy-dependent morphology support the scenario that inverse-Compton (IC) emission of an evolved pulsar wind nebula (PWN) associated with PSR J1907+0602 is responsible for the MGRO J1908+06 \(\gamma\)-ray emission with a best-fit true age of \(T=22\pm 9\) kyr and a magnetic field of \(B=5.4 \pm 0.8\ \mu\mathrm{G}\), assuming the distance to the pulsar \(d_{\mathrm{PSR}}=3.2\) kpc. |
