Description
Regions of enhanced synchrotron emission with unusually hard spectra – known as
the non-thermal radio filaments – have attracted significant interest due difficulty in
modeling their synchrotron spectra with astrophysical electron injection spectra. We
show that the synchrotron emission from these regions may be connected to recent
Fermi-LAT observations showing excess gamma-ray emission near the galactic center.
Specifically, we find that a light, and leptophilic dark matter profile previously
employed to explain the Fermi gamma-ray excess will inject leptons with the correct
intensity and spectrum to explain the synchrotron signal observed in the filamentary
arcs.
