Description

The presence of all-sky, diffuse gamma-ray emission has been known for several decades, but its origin remains an open question. While astrophysical sources almost certainly contribute, dark matter annihilation in galaxies outside our own may also leave an imprint. I will present results from a series of studies aimed at extracting such dark matter signals with publicly available data from the Fermi Large Area Telescope. My primary focus will be on a new method that takes advantage of galaxy surveys, such as 2MASS, to provide thousands of targets in which to search for signals of dark matter.
