Kes 41 is among the Galactic supernova remnants (SNRs) proposed to bephysically linked to $\gamma$-ray emission at GeV energies. Although notconclusively, the nature of the $\gamma$-ray photons has been explained bymeans of hadronic collisions of particles accelerated at the SNR blast wavewith target protons in an adjacent molecular clump. We performed an analysis ofFermi-Large Area Telescope (LAT) data of about 9 years to assess the origin ofthe $\gamma$-ray emission. To investigate this matter we also used spectralmodelling constraints from the physical properties of the interstellar mediumtowards the $\gamma$-ray emitting region along with a revised radio continuumspectrum of Kes 41 ($\alpha = -0.54 \pm 0.10$, $S\propto\nu^{\alpha}$). Wedemonstrated that the $\gamma$-ray fluxes in the GeV range can be explainedthrough bremsstrahlung emission from electrons interacting with the surroundingmedium. We also consider a model in which the emission is produced bypion-decay after hadronic collisions, and confirmed that this mechanism cannotbe excluded.
