The characteristics of the Galactic Center Excess (GCE) emission observed in gamma-ray energies -- especially the morphology of the GCE -- remain a hotly debated subject. The manner in which the dominant diffuse gamma-ray background is modeled has been claimed to have a determining effect on the preferred morphology. In this work, we compare two distinct approaches to the galactic diffuse gamma-ray emission background: the first approach models this emission through templates calculated from a sequence of well-defined astrophysical assumptions, while the second approach divides surrogates for the background gamma-ray emission into cylindrical galactocentric rings with free independent normalizations. At the latitudes that we focus on, we find that the former approach works better, and that the overall best fit is obtained for an astrophysically motivated fit when the GCE follows the morphology expected of dark matter annihilation. Quantitatively, the improvement compared to the best ring-based fits is roughly 6500 in the chi^2 and roughly 4000 in the log of the Bayesian evidence.

Galactic Center gamma-ray excess from a generic triaxial halo
Fermi-LAT fits show the Galactic Center gamma-ray excess keeps its spectrum and cuspiness under triaxial/tilted dark matter halo templates, but its morphology prefers a flipped-tilt halo and disfavors a stellar-halo profile.

Dark Sector Electroweak Baryogenesis In Light Of The Galactic Center Excess
A dark-sector electroweak baryogenesis model with a ~50 GeV fermionic dark matter candidate can simultaneously match the baryon asymmetry, the dark matter relic density, and (at ~2 sigma) the galactic center gamma-ray...

Fermi-LAT Galactic Center Excess morphology of dark matter in simulations of the Milky Way galaxy
The manuscript body is a different paper (b → c semileptonic sum rules) and contains none of the claimed dark matter gamma-ray morphology analysis, so the abstract's prediction is unsupported.
