Link to paper: https://arxiv.org/abs/2507.07209 > 20 GeV halo-like excess of the Galactic diffuse emission and implications for dark matter annihilation > Fifteen years of the Fermi Large Area Telescope (LAT) data in the halo region of the Milky Way (MW) are analyzed to search for gamma rays from dark matter annihilation. Gamma-ray maps within the region of interest (|l|≤60∘, 10∘≤|b|≤60∘) are modeled using point sources, the GALPROP models of cosmic-ray interactions, isotropic background, and templates of Loop I and the Fermi bubbles, and then the presence of a halo-like component is further…

The theory is that dark matter can decay or annihilate and when that happens there is an emission. A dark, or perhaps, nocturnal, emission if you will, which can be detected. https://arxiv.org/abs/2507.07209
