The Milky Way’s weird gamma-ray glow may be dark matter after all
Researchers using machine learning have re-evaluated the Galactic Center Excess, a mysterious gamma-ray glow in the Milky Way. The study suggests that dark matter remains a plausible explanation for the signal, challenging previous theories that favored pulsars.
Why it matters
Understanding the origin of this signal could provide a breakthrough in identifying dark matter, which constitutes a significant portion of the universe's mass.
Researchers from the University of Vienna and Lawrence Berkeley National Laboratory have turned to machine learning to take a fresh look at one of astrophysics' most debated mysteries. Their focus was the Galactic Center Excess (GCE), a faint, roughly spherical glow of gamma rays surrounding the center of the Milky Way. For more than a decade, scientists have debated what is producing this unusual signal. The new findings suggest that dark matter remains a viable explanation and cannot yet be dismissed. The study was published in Physical Review Letters .
