Neighbors, Not Kin: Kinematic evidence for tidal tails from NGC 7492 along the Sagittarius stream
Camila Navarrete, Ãlvaro Rojas-Arriagada, Andrés E. Piatti +8
The formation, extension, and morphology of extra-tidal stars around globular clusters depend on the internal kinematics of the host cluster and the Galactic potential. Tracing the…
The metal-poor tail of the APOGEE survey I. Uncovering [Fe/H] < -2.5 stars from the inner Galaxy to the Magellanic Clouds
M. Montelius, E. Starkenburg, H. Woudenberg +9
In the search for metal-poor stars, large spectroscopic surveys are an invaluable tool. However, the spectra of metal-poor stars can be difficult to analyse because of the relative…
Searching for new Hypervelocity Stars with Gaia DR3 and VLT/FORS2 Spectroscopy
Julio A. Carballo-Bello, Pau Ramos, Jesús M. Corral-Santana +5
Hypervelocity stars are unique objects moving through the Milky Way at speeds exceeding the local escape velocity, providing valuable insights into the Galactic gravitational poten…
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…
