Search for gamma-ray line features from Milky Way satellites with Fermi LAT Pass 8 data
With 91 months of the publicly available Fermi LAT Pass 8 data, we analyze the gamma-ray emission from the Milky Way satellites to search for potential line signals due to the annihilation of dark matter particles into double photons. The searched targets include a sample of dwarf spheroidal galaxies, the …
