The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
A stellar stream remnant of a globular cluster below the metallicity floor
Nicolas F. Martin, Kim A. Venn, David S. Aguado +23
Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures formed in the early un…
Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
Jaclyn Jensen, Guillaume Thomas, Alan W. McConnachie +9
We examine the spatial clustering of blue horizontal branch (BHB) stars from the -band of the Canada-France Imaging Survey (CFIS, a component of the Ultraviolet Near-In…
Zero-metallicity hypernova uncovered by an ultra metal-poor star in the Sculptor dwarf spheroidal galaxy
Ása Skúladóttir, Stefania Salvadori, Anish M. Amarsi +9
Although true metal-free "Population III" stars have so-far escaped discovery, their nature, and that of their supernovae, is revealed in the chemical products left behind in the n…
The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
CAPOS: The bulge Cluster APOgee Survey I. Overview and initial ASPCAP results
Doug Geisler, Sandro Villanova, Julia E. O'Connell +39
Context. Bulge globular clusters (BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational d…
