  The Fermi Large Area Telescope data appear to have an excess of gamma rays
from the inner 150 pc of the Galactic Center (GC). The main explanations
proposed for this are: an unresolved population of millisecond pulsars (MSPs),
dark matter (DM) annihilation, and cosmic rays interacting with molecular
clouds at the GC. In this conference proceeding article we highlight some of
the cosmic-ray results of [1]. The MSPs and DM explanations were modeled with
spatial templates well fitted by the square of a generalized
Navarro-Frenk-White (NFW) profile with inner slope $\gamma=1.2$. The cosmic-ray
option was modeled with a 20-cm continuum emission Galactic Ridge template. A
template based on the HESS residuals were shown to give similar results. The
gamma-ray excess was found to be best fit by a combination of the generalized
NFW squared template and a Galactic Ridge template. We also found the spectra
of each template was not significantly affected in the combined fit and is
consistent with previous single template fits. Due to the ridge like morphology
of the molecular gas at the GC, the cosmic-ray option was not able to explain
all the excess gamma rays, indicating that DM annihilation and/or an unresolved
population of MSPs is also needed.
