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…

Impact of the Galactic bar on tidal streams within the Galactic disc: The case of the tidal stream of the Hyades

Guillaume F. Thomas, Benoit Famaey, Giacomo Monari +5

Tidal streams of disrupted clusters are routinely detected in the halo of the Milky Way. It was recently shown that tidal streams of open clusters can now also be detected within t…

The Pristine survey -- XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry

Nicolas F. Martin, Else Starkenburg, Zhen Yuan +38

We used the spectro-photometric information of ~219 million stars from Gaia's DR3 to calculate synthetic, narrow-band, metallicity-sensitive CaHK magnitudes that mimic the observat…

Do old globular clusters in low mass galaxies disprove modified gravity?

Michal Bílek, Hongsheng Zhao, Benoit Famaey +6

The controversy "dark matter vs. modified gravity" constitutes a major topic of discussion. It was proposed that dynamical friction could be used to discriminate between the two al…

Disk galaxies are self-similar: the universality of the HI-to-Halo mass ratio for isolated disks

Marie Korsaga, Benoit Famaey, Jonathan Freundlich +7

Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.…

Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions

Clément Stahl, Yohan Dubois, Benoit Famaey +4

Collisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, wit…
