Detection of Gamma-Rays from the Protostellar Jet in the HH 80–81 System

Considering that the existence of relativistic particles in protostellar jet has been confirmed by detection linearly polarized radio emission from HH 80-81 jet, we search for gamma-rays system using ten-year {\it Fermi}-LAT observations. A significant point-like $\gamma$-ray excess is found direction with Test-Statistic (TS) value $>$100, which likely produced jet. The spectrum extends only to 1 GeV a photon index 3.5. No variability gamma-ray emission. It discussed properties suffice producing observed $\gamma$-rays.
