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…
SPLUS J142445.34-254247.1: An R-Process Enhanced, Actinide-Boost, Extremely Metal-Poor star observed with GHOST
Vinicius M. Placco, Felipe Almeida-Fernandes, Erika M. Holmbeck +33
We report on the chemo-dynamical analysis of SPLUS J142445.34-254247.1, an extremely metal-poor halo star enhanced in elements formed by the rapid neutron-capture process. This sta…
Effect of low-mass galaxy interactions on their star formation
Smitha Subramanian, Chayan Mondal, Venu Kalari
According to the cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected.…
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…
Understanding the chemical evolution of blue Edge-on Low Surface Brightness Galaxies
Tian-wen Cao, Hong Wu, Gaspar Galaz +4
We present a sample of 330 blue edge-on low surface brightness galaxies (ELSBGs). To understand the chemical evolution of LSBGs, we derived the gas-phase abundance and the [/Fe]…
