1. What are the contributions in "Studying the nature of the unidentified gamma-ray source hess j1841−055 with the magic telescopes" ?
The authors investigate the physical nature and origin of the gamma-ray emission from the extended source HESS J1841−055 observed at TeV and GeV energies.. Using both Fermi-LAT and MAGIC, the authors study both the spectral and energy-dependent morphology of the source for almost four decades of energy.. The authors find that the extended emission at GeV–TeV energies is best described by more than one source model.. The authors also perform the first energy-dependent analysis of the HESS J1841−055 region at GeV–TeV.. Moreover, the authors find that a significant curvature is present in the combined observed spectrum of MAGIC and Fermi-LAT.. 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.

2. How many h of data are selected for analysis?
After quality cuts, which account for hardware problems, unusual rates, and bad atmospheric conditions, ∼34 h of high-quality, dark-time data are selected for further analysis.

3. What is the gamma-ray flux at TeV energies?
The gamma-ray flux at TeV energies, a factor of 2 lower than the Crab nebula flux, is required to have S0 = (L0/1037 erg s−1)(d/1 kpc)−2 ≥ 10−3, where L0 and d are the luminosity and distance of the source, respectively (Aharonian 2004).

4. What is the effect of the injection of relativistic electrons in the interstellar magnetic?
TeV emission is an effective product of the IC mechanism for such isolated pulsars, with the injection of relativistic electrons in the interstellar magnetic field, which is about 3 μG.
