Dark matter cannot be ruled out as cause of gamma ray glow at the Milky Way's center, machine learning shows

Researchers from the University of Vienna and Lawrence Berkeley National Laboratory used machine learning to reassess the Galactic Center Excess (GCE), a gamma-ray glow at the Milky Way's center, which has been debated for over a decade. Their analysis, published in Physical Review Letters, suggests that dark matter could still be a viable explanation due to the faintness of potential millisecond pulsar sources, indicating more research is needed before ruling out dark matter as a cause.
