We report the discovery of eight new Milky Way companions in ∼ 1800 deg 2 ?> of optical imaging data collected during the first year of the Dark Energy Survey (DES). Each system is identified as a statistically significant over-density of individual stars consistent with the expected isochrone and luminosity function of an old and metal-poor stellar population. The objects span a wide range of absolute magnitudes (MV from − 2.2 ?> to − 7.4 mag ?> ), physical sizes ( 10 − 170 pc ?> ), and…
