GHOST commissioning science results -- IV: Chemodynamical analyses of Milky Way satellites Sagittarius II and Aquarius II
Daria Zaremba, Kim Venn, Christian R. Hayes +28
We present Gemini/GHOST high-resolution spectra of five stars observed in two low surface brightness Milky Way satellites, Sagittarius II (Sgr2) and Aquarius II (Aqu2). For Aqu2, t…
GHOST Commissioning Science Results III: Characterizing an iron-poor damped Lyman system
Trystyn A. M. Berg, Christian R. Hayes, Stefano Cristiani +20
The Gemini High-resolution Optical SpecTrograph (GHOST) is a new echelle spectrograph available on the Gemini-South telescope as of Semester 2024A. We present the first high resolu…
Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk
Anya Dovgal, Kim A. Venn, Federico Sestito +31
Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…
GHOST Commissioning Science Results II: a very metal-poor star witnessing the early Galactic assembly
Federico Sestito, Christian R. Hayes, Kim A. Venn +25
This study focuses on Pristine (hereafter P180956, ), a star selected from the Pristine Inner Galaxy Survey (PIGS), and followed-up…
GHOST Commissioning Science Results: Identifying a new chemically peculiar star in Reticulum II
Christian R. Hayes, Kim A. Venn, Fletcher Waller +79
The Gemini High-resolution Optical SpecTrograph (GHOST) is the newest high resolution spectrograph to be developed for a large aperture telescope, recently deployed and commissione…
