Dr. Ajello featured in “NASA’s Fermi Mission Expands its Search for Dark Matter”

Congratulations to our very own Dr. Marco Ajello for being featured in the NASA story, NASA’s Fermi Mission Expands its Search for Dark Matter. Dr. Ajello and his collaborators from NASA’s Fermi Mission utilized data from the Large Area Telescope (LAT) to analyze possible sources of the extragalactic gamma-ray background (EGB). In a paper published in the April 14 issue of Physical Review Letters, Dr. Ajello and his colleague Mattia Di Mauro at SLAC National Accelerator Laboratory in California concluded that nearly all of the EGB could be accounted for by blazars and other discrete sources of gamma-rays. This has relevance to dark matter research as it places limits on how much of the EGB could be be a result of dark matter interactions.
