Search for Gamma-Ray Emission from DES Dwarf Spheroidal Galaxy Candidates with Fermi-LAT Data

Understand

Due to their proximity, high dark-matter content, and apparent absence of non-thermal processes, Milky Way dwarf spheroidal satellite galaxies (dSphs) are excellent targets for the indirect detection of dark matter.

• Recently, eight new dSph candidates were discovered using the first year of data from the Dark Energy Survey (DES).
• We searched for gamma-ray emission coincident with the positions of these new objects in six years of Fermi Large Area Telescope data.
• We found no significant excesses of gamma-ray emission.
