In LSST DC2 simulations, EROSE recovers the highest fraction of injected Milky Way dwarf satellites with u,g photometry, while g,r,i recovers the most total systems because of its larger usable sky area.

abstract
We have used the publicly released Dark Energy Survey data to hunt for new satellites of the Milky Way in the Southern hemisphere. Our search yielded a large number of promising candidates. In this paper, we announce the discovery of 9 new unambiguous ultra-faint objects, whose authenticity can be established with the DES data alone. Based on the morphological properties, three of the new satellites are dwarf galaxies, one of which is located at the very outskirts of the Milky Way, at a distance of 380 kpc. The remaining 6 objects have sizes and luminosities comparable to the Segue~1 satellite and can not be classified straightforwardly without follow-up spectroscopic observations. The satellites we have discovered cluster around the LMC and the SMC. We show that such spatial distribution is unlikely under the assumption of isotropy, and, therefore, conclude that at least some of the new satellites must have been associated with the Magellanic Clouds in the past.

Resolved HI observations of six baryon-dominated dwarf galaxy candidates show four are dark-matter deficient with high baryon efficiency, two in isolated environments without tidal signs.
Photometric analysis yields metallicity distributions for 3917 stars across 12 faint Milky Way satellites, showing average [Fe/H] ~ -2.3 dex, 170 EMP candidates, and no gradients in ultra-faint systems.
