Snapshots of r-process production in the Milky Way disk
Sarah G. Kane, Stephanie Monty, Madeleine McKenzie +9
Stars enhanced in heavy neutron capture elements like europium (Eu) provide a window into the rarest and most exotic nucleosynthetic events. Most Eu-enhanced stars discovered thus…
The Ashes of Supermassive Stars: Globular Cluster-like Aluminum Enhancement in Little Red Dots
V. Kokorev, J. Chisholm, R. P. Naidu +16
The relative abundances of elements in galaxies serve as fossil records of the physical conditions and processes by which they were forged. While the Big Bang produced only the lig…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
Magnesium isotope ratios in Milky Way and dwarf galaxy stars
M. McKenzie, S. Monty, D. Yong +8
Under the assumption of hierarchical galaxy formation, dwarf galaxies are the closest existing analogues to the high-redshift protogalaxies that merged to form the Milky Way. These…
The complex stellar system M 22: constraining the chemical enrichment from AGB stars using magnesium isotope ratios
M. McKenzie, D. Yong, A. I. Karakas +8
The complex star cluster M 22 (NGC 6656) provides a unique opportunity for studying slow neutron-capture (s-process) nucleosynthesis at low metallicity due to its two stellar group…
The complex stellar system M 22: confirming abundance variations with high precision differential measurements
M. McKenzie, D. Yong, A. F. Marino +8
M 22 (NGC 6656) is a chemically complex globular cluster-like system reported to harbour heavy element abundance variations. However, the extent of these variations and the origin…
Globular cluster abundance patterns inherited from giant molecular clouds
William McClymont, Vasily Belokurov, Sandro Tacchella +16
Globular clusters exhibit large star-to-star variations and anticorrelations in their light element abundances that are commonly interpreted in terms of in-cluster self-enrichment,…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
