The Pristine Dwarf Galaxy Survey -- VII. The metallicity distributions of 12 Milky Way faint satellites

S. Taibi, P. Jablonka, N. Longeard +10

Spectroscopic studies of ultra-faint dwarf galaxies are typically limited to small samples of stars due to the scarcity of sufficiently bright targets. The small number statistics…

The Pristine Dwarf-Galaxy survey -- VI. A VLT/FLAMES spectroscopic study of the dwarf galaxy Boötes II

Nicolas Longeard, Pascale Jablonka, Giuseppina Battaglia +4

The Milky Way has a large population of dwarf galaxy satellites. Their properties are sensitive to both cosmology and the physical processes underlying galaxy formation, but these…

Stellar Metallicities and Gradients in the Faint M31 Satellites Andromeda XVI and Andromeda XXVIII

Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +11

We present stellar metallicity measurements in two faint M31 dwarf galaxies, Andromeda XVI () and Andromeda XXVIII () derived using metallicity-se…

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…

Stellar Metallicities and Gradients in the Isolated, Quenched Low-Mass Galaxy Tucana

Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +10

We measure the metallicities of 374 red giant branch (RGB) stars in the isolated, quenched dwarf galaxy Tucana using Hubble Space Telescope (HST) narrow-band (F395N) Calcium H & K…

Gaia's brightest very metal-poor (VMP) stars. Metallicity catalogue of a thousand VMP stars from Gaia's radial velocity spectrometer spectra

Akshara Viswanathan, Else Starkenburg, Tadafumi Matsuno +10

Context. Gaia DR3 has offered the scientific community a remarkable dataset of approximately one million spectra acquired with the Radial Velocity Spectrometer (RVS) in the Calcium…
