Colors of Irregular Satellites of Saturn with DECam

Abstract
We report g-r and r-i new colors for 21 Saturn Irregular Satellites, among them, 4 previously unreported. This is the highest number of Saturn Irregular satellites reported in a single survey. These satellites were measured by "stacking" their observations to increase their signal without trailing. This work describes a novel processing algorithm that enables the detection of faint sources under significant background noise and in front of a severely crowded field. Our survey shows these new color measurements of Saturn Irregular Satellites are consistent with other Irregular Satellites populations as found in previous works and reinforcing the observation that the lack of ultra red objects among the irregular satellites is a real feature that separates them from the trans-Neptunian objects (their posited source population).
