Dark Matter Sighting Gets a Reprieve in New Analysis

Ultimately they learned that the unexpected pulsars threw off the analysis, leading to the erroneous conclusion that this dark matter–stuffed galaxy had little dark matter. Moreover, the kind of dark matter particles that would be needed to produce the AMS data are approximately the same kind of dark matter particles that would be needed to produce the observed gamma-ray glow in the center of the galaxy. A clearer point for dark matter, however, would be if AMS or another high-altitude experiment found heavier, lumbering antimatter particles, which cosmic rays rarely produce.
