r-process Abundance Patterns in the Globular Cluster M92

Evan N. Kirby, Alexander P. Ji, Mikhail Kovalev

Whereas light element abundance variations are a hallmark of globular clusters, there is little evidence for variation in neutron-capture elements. A significant exception is M15,…

The Prevalence of the -bimodality: First JWST -abundance Results in M31

David L. Nidever, Karoline Gilbert, Erik Tollerud +8

We present initial results from our JWST NIRSpec program to study the -abundances in the M31 disk. The Milky Way has two chemically-defined disks, the low- and high- disks…

On the Metallicities and Kinematics of the Circumgalactic Media of Damped Ly Systems at

Stephanie M. Urbano Stawinski, Kate H. R. Rubin, J. Xavier Prochaska +7

We use medium- and high-resolution spectroscopy of close pairs of quasars to analyze the circumgalactic medium (CGM) surrounding 32 damped Ly absorption systems (DLAs). The prim…

The Hubble Space Telescope Survey of M31 Satellite Galaxies II. The Star Formation Histories of Ultra-Faint Dwarf Galaxies

A. Savino, D. R. Weisz, E. D. Skillman +34

We present the lifetime star formation histories (SFHs) for six ultra-faint dwarf (UFD; , ) satellite galaxies of M31 based on…
