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…
SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova
W. V. Jacobson-Galan, L. Dessart, R. Margutti +65
We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…
Validating Stellar Abundance Measurements from Multi-Resolution Spectroscopy
Nathan R. Sandford, Daniel R. Weisz, Yuan-Sen Ting
Large-scale surveys will provide spectroscopy for 50 million resolved stars in the Milky Way and Local Group. However, these data will have a high degree of heterogeneity and…
From Carbon to Cobalt: Chemical compositions and ages of quiescent galaxies
Aliza G. Beverage, Mariska Kriek, Charlie Conroy +5
We present elemental abundance patterns (C, N, Mg, Si, Ca, Ti, V, Cr, Fe, Co, and Ni) for a population of 135 massive quiescent galaxies at with ultra-deep rest-frame op…
