Tracing the formation of the Milky Way through ultra metal-poor stars
Federico Sestito, Nicolas Longeard, Nicolas F. Martin +11
We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultr…
Mirach's Goblin: Discovery of a dwarf spheroidal galaxy behind the Andromeda galaxy
David Martinez-Delgado, Eva K. Grebel, Behnam Javanmardi +9
It is of broad interest for galaxy formation theory to carry out a full inventory of the numbers and properties of dwarf galaxies in the Local Volume, both satellites and isolated…
Pristine Dwarf-Galaxy Survey I: A detailed photometric and spectroscopic study of the very metal-poor Draco II satellite
Nicolas Longeard, Nicolas Martin, Else Starkenburg +17
We present a detailed study of the faint Milky Way satellite Draco II (Dra II) from deep CFHT/MegaCam broadband and photometry and narrow-band metallicity-sensitive CaHK ob…
The Pristine Survey IV: Approaching the Galactic metallicity floor with the discovery of an ultra metal-poor star
Else Starkenburg, David S. Aguado, Piercarlo Bonifacio +22
The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Gala…
Current velocity data on dwarf galaxy NGC1052-DF2 do not constrain it to lack dark matter
Nicolas F. Martin, Michelle L. M. Collins, Nicolas Longeard +1
It was recently proposed that the globular cluster system of the very low surface-brightness galaxy NGC1052-DF2 is dynamically very cold, leading to the conclusion that this dwarf…
