A spatially resolved view of Fast Radio Burst host metallicities with Integral-field Spectroscopy
Sunil Simha, Hsiao-Wen Chen, Wen-fai Fong +15
Magnetar sources are the leading theory for Fast Radio Burst (FRB) progenitors. If magnetars are indeed the dominant sources, we may thus expect any metallicity preference for magn…
Sr and Ba yields of the First Generation(s) of stars: Constraints from metal-poor stars
Sarah Hughes, Anna Frebel, Xiaowei Ou +6
We present our chemical abundance analysis of ten new extremely metal-poor stars with $-4.05\leq\mbox{[Fe/H]}\leq-2.33$, based on high-resolution (R ) Magellan/MIKE spe…
Carbon Abundances in Metal-Poor Stars Reveal Distinct Galaxy and Star Formation Pathways in the Early Universe
Alexander Yelland, Anna Frebel, Xiaowei Ou +2
Carbon-enhanced metal-poor (CEMP; with and ) stars preserve information about early chemical enrichment, low-mass star formation, and th…
The WEAVE acquisition and guiding software: pattern recognition-based acquisition and multi-fibre guiding
Emanuel Gafton, Gavin B. Dalton, Don Carlos Abrams +19
We present the architecture, implementation, and on-sky validation of the fully automated acquisition and guiding system (AG) developed for the WEAVE instrument on the William Hers…
