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 Faint M31 Satellites Andromeda XVI and Andromeda XXVIII
Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +11
We present stellar metallicity measurements in two faint M31 dwarf galaxies, Andromeda XVI () and Andromeda XXVIII () derived using metallicity-se…
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…
Metallicity Distribution Functions of 13 Ultra-Faint Dwarf Galaxy Candidates from Hubble Space Telescope Narrowband Imaging
Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +10
We present uniformly measured stellar metallicities for 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; to ) using narrowband CaHK (F395N) imagi…
Strong Outflows and Inefficient Star Formation in the Reionization-era Ultra-faint Dwarf Galaxy Eridanus II
Nathan R. Sandford, David H. Weinberg, Daniel R. Weisz +1
We present novel constraints on the underlying galaxy formation physics (e.g., mass loading factor, star formation history, metal retention) at for the low-mass ($M_*\s…
Metallicity Distribution Function of the Eridanus~II Ultra-Faint Dwarf Galaxy from Hubble Space Telescope Narrow-band Imaging
Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +9
We use deep narrowband Ca H&K () imaging taken with the Hubble Space Telescope (HST) to construct the metallicity distribution function (MDF) of Local Group (LG) ultra-faint…
Dynamical Histories of the Crater II and Hercules Dwarf Galaxies
Sal Wanying Fu, Joshua D. Simon, Alex G. Alarcón Jara
We investigate the possibility that the dwarf galaxies Crater II and Hercules have previously been tidally stripped by the Milky Way. We present Magellan/IMACS spectra of candidate…
The Origin of the 300 km s Stream Near Segue 1
Sal Wanying Fu, Joshua D. Simon, Matthew Shetrone +12
We present a search for new members of the 300 km s stream (300S) near the dwarf galaxy Segue 1 using wide-field survey data. We identify 11 previously unknown bright stream…
