Caption: Figure 3.

Radial profile of the H2 ionization rate in the CMZ for XDM models as a function of cylindrical distance R from the GC. Here, the mass splitting is fixed to Δm = 4 MeV, and different line styles indicate different XDM masses from 1 to 2 TeV. All cases use NFW and the best-fit σmr from the 511 keV fit in Figure 1.
