  We enlarge the set of recipes and ingredients at disposal of any poor
particle physicist eager to cook up signatures from weak-scale Dark Matter
models by computing two secondary emissions due to DM particles annihilating or
decaying in the galactic halo, namely the radio signals from synchrotron
emission and the gamma rays from bremsstrahlung. We consider several magnetic
field configurations and propagation scenarios for electrons and positrons. We
also provide an improved energy loss function for electrons and positrons in
the Galaxy, including synchrotron losses in the different configurations,
bremsstrahlung losses, ionization losses and Inverse Compton losses with an
updated InterStellar Radiation Field.
