Searching for and characterizing halo substructures with the GALAH DR4 survey
Iryna Kushniruk, Kristopher Youakim, Karin Lind +12
Recent studies show that the Milky Way stellar halo is composed of populations of different origins, shaped by multiple accretion events. To better understand the formation of the…
Identifying substructure associations in the Milky Way halo using chemo-kinematic tagging
Kris Youakim, Karin Lind
The Milky Way halo has been built-up over cosmic time through the accretion and dissolution of star clusters and dwarf galaxies as well as through their complex interactions with t…
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…
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…
