Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.

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.
The MAGIC survey provides photometric metallicities for RGB stars over ~3000 deg² using CaHK narrow-band imaging plus DELVE g,r,i data, recovering 13/14 known ultra-faint dwarfs and confirming a distant Reticulum II member.
