The Pristine Inner Galaxy Survey (PIGS) XI: Revealing the chemical evolution of the interacting Sagittarius dwarf galaxy
Sara Vitali, Alvaro Rojas-Arriagada, Paula Jofré +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is a satellite orbiting the Milky Way that has experienced multiple stripping events due to tidal interactions with our Galaxy. I…
Icarus revisited: An Ancient, Metal-poor Accreted Stellar Stream in the Disk of the Milky Way
Paola Re Fiorentin, Alessandro Spagna, Mario G. Lattanzi +2
The search for accreted satellites in the Galactic disk is a challenging task, to which Gaia plays a crucial role in synergy with ground-based spectroscopic surveys. In 2021, Re Fi…
Full abundance study of two newly discovered barium giants
Sara Vitali, Ana Escorza, Ditte Slumstrup +1
Barium (Ba) stars are chemically peculiar stars that show enhanced surface abundances of heavy elements produced by the slow-neutron-capture process, the so-called s-process. These…
An ancient system hidden in the Galactic plane?
Federico Sestito, Emma Fernandez-Alvar, Rebecca Brooks +19
We analyse high signal-to-noise ESPaDOnS/CFHT spectra of 20 very metal-poor stars (VMP; [Fe/H]~) in the solar neighbourhood (within kpc), selected to be on planar or…
The Pristine Survey -- XXVII. Journey to the Galactic outskirts -- Mapping the outer halo red giant stars down to the very metal-poor end
Akshara Viswanathan, Amanda Byström, Else Starkenburg +14
Context: In the context of Galactic archaeology, the outer halo remains relatively unexplored with respect to its metallicity distribution, merger debris, and the abundance of know…
The Pristine survey XXIV: The Galactic underdogs -- Dynamic tales of a Milky Way metal-poor population
Isaure González Rivera de La Vernhe, Vanessa Hill, Georges Kordopatis +12
Through the chemodynamical characterisation of metal-poor stars, one can efficiently probe the early history of the Milky Way. We aim at decontaminating a sample of 3M giant…
The Pristine Inner Galaxy Survey (PIGS) IX. The largest detailed chemical analysis of very metal-poor stars in the Sagittarius dwarf galaxy
Federico Sestito, Sara Vitali, Paula Jofre +16
The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first generations of supernovae. T…
The Pristine Inner Galaxy Survey (PIGS) X. Probing the early chemical evolution of the Sagittarius dwarf galaxy with carbon abundances
Federico Sestito, Anke Ardern-Arentsen, Sara Vitali +6
We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. Our sample from the \textit{Pristine} Inner Galaxy Survey (PIGS) i…
The Pristine survey: XXV. The very metal-poor Galaxy: Chemodynamics through the follow-up of the Pristine-Gaia synthetic catalogue
Akshara Viswanathan, Zhen Yuan, Anke Ardern-Arentsen +27
The Pristine-\textit{Gaia} synthetic catalogue provides reliable photometric metallicities for 30 million FGK stars using the Pristine survey model and Gaia XP spectra. We pe…
