EROSE: An algorithm searching for resolved Local Group satellites. The impact of combining different photometric bands on the detectability of Milky Way satellites in the LSST
Samuel Rusterucci, Nicolas F. Martin, Else Starkenburg
Systematic searches for ultra-faint Milky Way satellite galaxies typically combine local density estimators with colour-magnitude cuts, which are usually performed in 2D and have r…
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…
Reassessing the proper motions of M31/M33 with Gaia DR3. Unraveling systematic uncertainties
Samuel Rusterucci, Nicolas F. Martin, Else Starkenburg +1
We provide an updated inference of the proper motion of M31 using the Gaia DR3 proper motions of bright stars from the disc of M31. By refining the motion of the quasar reference f…
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…
