Understanding Stellar Mass-Metallicity and Size Relations in Simulated Ultra-Faint Dwarf Galaxies
Minsung Go, Myoungwon Jeon, Yumi Choi +7
Reproducing the physical characteristics of ultra-faint dwarf galaxies (UFDs) in cosmological simulations is challenging, particularly with respect to stellar metallicity and galax…

Stellar Metallicities and Gradients in the Isolated, Quenched Low-Mass Galaxy Tucana
Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +10
We measure the metallicities of 374 red giant branch (RGB) stars in the isolated, quenched dwarf galaxy Tucana using Hubble Space Telescope (HST) narrow-band (F395N) Calcium H & K…
