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 accreted Galaxy: An overview of TESS metal-poor accreted stars candidates
Danielle de Brito Silva, Paula Jofré, Clare Worley +2
The Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion history…
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…
On the evolutionary history of a simulated disc galaxy as seen by phylogenetic trees
Danielle de Brito Silva, Paula Jofré, Patricia B. Tissera +12
Phylogenetic methods have long been used in biology, and more recently have been extended to other fields - for example, linguistics and technology - to study evolutionary historie…
Unraveling UBC 274: a morphological, kinematical and chemical analysis of a disrupting open cluster
L. Casamiquela, J. Olivares, Y. Tarricq +8
We do a morphological, kinematic and chemical analysis of the disrupting cluster UBC 274 (2.5 Gyr, pc) to study its global properties. We use HDBSCAN to obtain a new membe…
J-PLUS: Detecting and studying extragalactic globular clusters -- the case of NGC 1023
Danielle de Brito Silva, Paula Coelho, Arianna Cortesi +19
Extragalactic globular clusters (GCs) are key objects for studying the history of galaxies. The arrival of wide-field surveys such as the Javalambre Photometric Local Universe Surv…
