Gamma-Ray Excess and the Minimal Dark Matter Model

TL;DR

This paper demonstrates that the minimal dark matter model can simultaneously explain gamma-ray excesses observed in the galactic center and Reticulum II, and predicts these regions will be tested by upcoming dark matter searches.

Contribution

It shows the minimal dark matter model can account for multiple gamma-ray excesses and highlights testable predictions for future experiments.

Findings

Minimal dark matter explains gamma-ray excesses in galactic center and Reticulum II.

Predicted parameter space will be tested by future dark matter searches.

The model provides a unified explanation for different gamma-ray signals.

Abstract

We point out that the gamma-ray excesses in the galactic center and in the dwarf galaxy Reticulum II can both be well explained within the simplest dark matter model. We find that the corresponding region of parameter space will be tested by direct and indirect dark matter searches in the near future.
