US EditionMysterious Glow in Milky Way Could Be Evidence of Dark Matter
Simulations by Johns Hopkins researchers show gamma ray signals matching dark matter collisions, keeping pulsars as an alternative source; new telescopes aim to resolve the debate.
- DOI: 10.48550/arxiv.2508.06314 reports Johns Hopkins simulations whose dark-matter maps matched Fermi Gamma-ray Space Telescope data, suggesting dark matter could produce the galactic-centre glow.
- For decades the glow has stumped researchers, with two rival explanations: annihilating WIMPs and a yet-unobserved population of millisecond pulsars causing the galactic-centre gamma-ray excess.
- Using supercomputers, Silk and an international research team incorporated Milky Way formation history and realistic dark-matter collisions to produce simulations matching the gamma-ray excess's shape and properties.
- Researchers plan experiments to test whether gamma rays are pulsar emissions or dark-matter products, while the Cherenkov Telescope Array's higher-resolution data could provide the first direct evidence for dark matter.
- In recent years the dark matter explanation lost favour after WIMP searches failed, but new simulations revive the dark-matter option despite the GCE’s flattened shape and remaining ambiguities in dwarf galaxies circling the Milky Way.

In astrophysics and physical cosmology, dark matter is called a type of matter that is estimated at approximately 85% of the matter of the universe, and that is not dark energy, barionic matter (ordinary matter) or neutrinos.Now, scientists are closer to confirming the existence of dark matter after having detected a diffuse glow of gamma rays near the center of our galaxy, as the Reuters agency gathers. Scientists rely on the existence of dark …
According to a recent modeling study, gamma rays coming from the center of the Milky Way may indicate that dark matter particles are colliding with each other.

Mysterious glow in Milky Way could be evidence of dark matter
Johns Hopkins researchers may have identified a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has stumped researchers for decades, as they've tried to discern whether the light comes from colliding particles of dark matter or quickly spinning neutron stars.
