Two ~6-8 Gyr old SMC clusters show sodium abundance differences of 0.18-0.24 dex between nitrogen-poor and nitrogen-rich red giants, matching the pattern seen in ancient globular clusters.
Globular cluster mass fractions, in-situ fractions, metallicity spreads, and spatial profiles in simulated compact galaxies can identify massive relic analogs with early assembly histories.
New abundance measurements for NGC 6723 align its chemical patterns with other metal-intermediate globular clusters rather than indicating a transition to metal-rich properties.
