Dark matter and the GeV gamma-ray sky
Prof. Markus Ackermann (Berlin)

Most of the matter in the universe is non-baryonic. While we can observe the gravitational effects of this dark matter on different scales in our universe, we haven’t identified its particle nature yet. However, many particle physics motivated candidates for dark matter are expected to produce a signal in GeV gamma rays, for example through pair-annihilation of such particles.

The Fermi Large Area Telescope (LAT), observing the GeV sky since 2008, is the most sensitive detector to search for such a gamma-ray signal. I will review the search strategies employed to identify potential signals from dark matter, compare their relative strengths and weaknesses, and show the latest results from the searches performed on Fermi LAT data.
