Statistical evidence has previously suggested that the Galactic Center GeV Excess (GCE) originates largely from point sources, and not from annihilating dark matter. We examine the impact of unmodeled source populations on identifying the true origin of the GCE using non-Poissonian template fitting (NPTF) methods. In a proof-of-principle example with simulated data, we discover that unmodeled sources in the Fermi Bubbles can lead to a dark matter signal being misattributed to point sources by the NPTF. We discover striking behavior consistent with a mismodeling effect in the real Fermi data, finding that large artificial injected dark matter signals are completely misattributed to point sources. Consequently, we conclude that dark matter may provide a dominant contribution to the GCE after all.

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.

Characterizing the Nature of the Unresolved Point Sources in the Galactic Center
The failure of NPTF to recover injected dark matter signals can be a natural consequence of unresolved point sources and diffuse background mismodeling, so it does not by itself invalidate the NPTF point-source interp...

A Novel Scheme for Dark Matter Annihilation Feedback in Cosmological Simulations
A donor-based scheme for dark matter annihilation feedback in cosmological simulations is implemented in Gizmo and validated against a receiver-based scheme, with a new Sedov-Taylor time-step limiter.

Semi-analytic Inference of Satellite Densities in the Cold Dark Matter Model Part II. Implications for Dark Matter Indirect Detection Constraints
Using SatGen and Jeans analyses, the authors find that J-factor modeling choices move Fermi dwarf-galaxy dark matter annihilation limits by a factor of 2–4 and that the highest-J dwarfs are already known and spatially...
