Informational corrections to the early-Universe radiation sector: CET Ω, WIMP freeze-out, and implications for a possible 20 GeV gamma-ray excess
Recent analyses of Fermi–LAT data have identified a nearly spherical, halo-like excess of gamma rays peaking at Eγ ∼ 20 GeV. If interpreted as dark matter annihilation, the excess directly probes the thermal freeze-out epoch, and therefore any non-standard corrections to the early-Universe expansion...
