The -Process Alliance: Enrichment of -process Elements in a Simulated Milky Way-like Galaxy

Yutaka Hirai, Timothy C. Beers, Young Sun Lee +11

We study the formation of stars with varying amounts of heavy elements synthesized by the rapid neutron-capture process (-process) based on our detailed cosmological zoom-in sim…

Discovery and Spectroscopic Confirmation of Aquarius III: A Low-Mass Milky Way Satellite Galaxy

W. Cerny, A. Chiti, M. Geha +37

We present the discovery of Aquarius III, an ultra-faint Milky Way satellite galaxy identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Base…

Probing the He II re-Ionization ERa via Absorbing C IV Historical Yield (HIERACHY) I: A Strong Outflow from a z~4.7 Quasar

Xiaodi Yu, Jiang-Tao Li, Zhijie Qu +7

Outflows from super-massive black holes (SMBHs) play an important role in the co-evolution of themselves, their host galaxies, and the larger scale environments. Such outflows are…

Dynamical masses and mass-to-light ratios of resolved massive star clusters -- II. Results for 26 star clusters in the Magellanic Clouds

Ying-Yi Song, Mario Mateo, John I. Bailey +5

We present spectroscopy of individual stars in 26 Magellanic Cloud (MC) star clusters with the aim of estimating dynamical masses and -band mass-to-light () ratios over a…

The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo -Process-Enhanced Stars Reveal a Shared Chemical-Evolution History

Dmitrii Gudin, Derek Shank, Timothy C. Beers +11

We derive dynamical parameters for a large sample of 446 -process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the…

Dynamical Masses and Mass-to-light Ratios of Resolved Massive Star Clusters. I. NGC 419 and NGC 1846

Ying-Yi Song, Mario Mateo, A. D. Mackey +4

As an introduction of a kinematic survey of Magellanic Cloud (MC) star clusters, we report on the dynamical masses and mass-to-light () ratios of NGC 419 (SMC) and NGC 1846 (L…
