Extracting the Gamma Ray Signal from Dark Matter Annihilation in the Galactic Center Region

Understand

The GLAST satellite mission will study the gamma ray sky with considerably greater exposure than its predecessor EGRET.

• In addition, it will be capable of measuring the arrival directions of gamma rays with much greater precision.
• These features each significantly enhance GLAST's potential for identifying gamma rays produced in the annihilations of dark matter particles.
• The combined use of spectral and angular information, however, is essential if the full sensitivity of GLAST to dark matter is to be exploited.
