The recent discovery of ten new dwarf galaxy candidates by the Dark EnergySurvey (DES) and the Panoramic Survey Telescope and Rapid Response System(Pan-STARRS) could increase the Fermi Gamma-Ray Space Telescope's sensitivityto annihilating dark matter particles, potentially enabling a definitive testof the dark matter interpretation of the long-standing Galactic Centergamma-ray excess. In this paper, we compare the previous analyses of Fermi datafrom the directions of the new dwarf candidates (including the relativelynearby Reticulum II) and perform our own analysis, with the goal ofestablishing the statistical significance of any gamma-ray signal from thesesources. We confirm the presence of an excess from Reticulum II, with aspectral shape that is compatible with the Galactic Center signal. Thesignificance of this emission is greater than that observed from 99.84% ofrandomly chosen high-latitude blank-sky locations, corresponding to a localdetection significance of 3.2 sigma. We improve upon the standard blank-skycalibration approach through the use of multi-wavelength catalogs, which allowus to avoid regions that are likely to contain unresolved gamma-ray sources.
