Description
The observation of PeVatrons is without doubt one of the major breakthroughs in gamma-ray astronomy. The quest for Galactic cosmic-ray candidates goes hand-in-hand with these discoveries. However, with the advent of the very high-energy observations, many new questions arise. In many of the reported sources the origin of the particles responsible for the gamma-ray is unclear, in many cases multiple candidates exist inside the confidence region of the observation. One special case is that of MGRO J1908+06 (LHAASO J1908+0621), where the very high-energy emission could be produced by a supernova remnant, a pulsar wind nebula or both. Using a espatial-dependent model we calculate the leptonic and hadronic emission from both sources to fit the observations. Using the multiwavelength data available, we analyse all the possible scenarios for explaining the very high-energy source and determine who is the most probable accelerator behind it.
