A comparative high-resolution spectroscopic analysis of in situ and accreted globular clusters
E. Ceccarelli, A. Mucciarelli, D. Massari +2
Globular clusters (GCs) are extremely intriguing systems that help in reconstructing the assembly of the Milky Way via the characterisation of their chemo-chrono-dynamical properti…
Predicting metallicities and carbon abundances from Gaia XP spectra for (carbon-enhanced) metal-poor stars
Anke Ardern-Arentsen, Sarah G. Kane, Vasily Belokurov +4
Carbon-rich (C-rich) stars can be found at all metallicities and evolutionary stages. They are often the result of mass-transfer from a companion, but some of the most metal-poor C…
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…
HR-GO I: Comprehensive NLTE abundance analysis of the Cetus stream
T. M. Sitnova, Z. Yuan, T. Matsuno +8
Dwarf galaxy streams encode vast amounts of information essential to understanding early galaxy formation and nucleosynthesis channels. Due to the variation in the timescales of st…
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 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…
The 33 M black hole Gaia BH3 is part of the disrupted ED-2 star cluster
E. Balbinot, E. Dodd, T. Matsuno +19
The Gaia Collaboration has recently reported the detection of a 33 M black hole in a wide binary system located in the Solar neighbourhood. Here we explore the relationship…
