How a Hidden Population of Pulsars May Leave the Milky Way Aglow

Dark matter is only known through indirect observations of disturbances or effects attributed to this theoretical matter. So-called ‘dark matter particles’ are thought to produce gamma emissions when they annihilate with one another. This has led many to believe that the gamma ray glow of our galaxy is due to the abundance of dark matter in the centre of the galaxy. However, using data from the Large Area Telescope on NASA’s Fermi Gamma-ray Space Telescope a team of astronomers have now suggested that the culprit may instead be a well-known population of pulsars. If this is confirmed, then the source of the gamma ray emission is solved but the search for dark matter goes on…
