Flattened Darkish Matter Might Clarify Mysterious Gamma-Ray Glow at Milky Method’s Core, Examine Finds

For greater than a decade, astronomers have been puzzled by the unusual high-energy glow that blazes from the centre of the Milky Method, an extra of gamma rays that can’t be defined by identified sources in its neighborhood. Now, new laptop simulations counsel that as a substitute of being spherical, the darkish matter round galaxies’ centres could also be “flattened,” doubtlessly fixing a part of the thriller. The findings, described on 16 October in Bodily Evaluation Letters, counsel that this discoidal association can create a radiation sample matching what has been seen. This doubtlessly revives a long-disputed principle linking darkish matter to the Milky Method’s vibrant central glow.
