Abstract
A number of groups have employed radio observations of the Galactic Center to
derive stringent constraints on annihilating dark matter. In this letter, we
show that electron energy losses in this region are likely to be dominated by
inverse Compton scattering on the interstellar radiation field, rather than by
synchrotron, relaxing the resulting constraints considerably. Strong convective
winds, which are well motivated by recent observations, may also significantly
weaken synchrotron constraints. After taking these factors into account, we
find that radio constraints on annihilating dark matter are orders of magnitude
less stringent than previously reported, and are generally weaker than those
derived from current gamma-ray observations.
