Abstract: Detecting and studying galactic gamma-ray sources emitting very-high energy
photons sheds light on the acceleration and propagation of cosmic rays
presumably created in these sources. Currently, there are few sources emitting
photons with energies exceeding 100 TeV. In this work we revisit the
unidentified source MGRO J1908+06, initially detected by Milagro, using an
updated H.E.S.S. dataset and analysis pipeline. The vicinity of the source
contains a supernova remnant and pulsars as well as molecular clouds. This
makes the identification of the primary source(s) of galactic cosmic rays as
well as the nature of the gamma-ray emission challenging, especially in light
of the recent HAWC and LHAASO detection of the high energy tail of its
spectrum. Exploiting the better angular resolution as compared to particle
detectors, we investigate the morphology of the source as well as its spectral
properties.
