      abstract     = {We investigate the physical nature and origin of the
                      gamma-ray emission from the extended source HESS J1841−055
                      observed at TeV and GeV energies. We observed HESS
                      J1841−055 at TeV energies for a total effective time of
                      43 h with the MAGIC telescopes, in 2012 and 2013.
                      Additionally, we analysed the GeV counterpart making use of
                      about 10 yr of Fermi-LAT data. Using both Fermi-LAT and
                      MAGIC, we study both the spectral and energy-dependent
                      morphology of the source for almost four decades of energy.
                      The origin of the gamma-ray emission from this region is
                      investigated using multiwaveband information on sources
                      present in this region, suggested to be associated with this
                      unidentified gamma-ray source. We find that the extended
                      emission at GeV–TeV energies is best described by more
                      than one source model. We also perform the first
                      energy-dependent analysis of the HESS J1841−055 region at
                      GeV–TeV. We find that the emission at lower energies comes
                      from a diffuse or extended component, while the major
                      contribution of gamma rays above 1 TeV arises from the
                      southern part of the source. Moreover, we find that a
                      significant curvature is present in the combined observed
                      spectrum of MAGIC and Fermi-LAT. The first multiwavelength
                      spectral energy distribution of this unidentified source
                      shows that the emission at GeV–TeV energies can be well
                      explained with both leptonic and hadronic models. For the
                      leptonic scenario, bremsstrahlung is the dominant emission
                      compared to inverse Compton. On the other hand, for the
                      hadronic model, gamma-ray resulting from the decay of
                      neutral pions $(π^0)$ can explain the observed spectrum.
                      The presence of dense molecular clouds overlapping with HESS
                      J1841−055 makes both bremsstrahlung and $π^0-decay$
                      processes the dominant emission mechanisms for the source.},
