Evidence for an excess of gamma rays with $\mathcal{\text{O}}(\mathrm{GeV})$ energy coming from the center of our galaxy has been steadily accumulating over the past several years. Recent studies of the excess in data from the Fermi telescope have cast doubt on an explanation for the excess arising from unknown astrophysical …
