Galactic Archaeology with Gaia
AJ Deason, V Belokurov - New Astronomy Reviews, 2024 - Elsevier
The Gaia mission has revolutionized our view of the Milky Way and its satellite citizens. The
field of Galactic Archaeology has been piecing together the formation and evolution of the …

Co-formation of the disc and the stellar halo
Using a large sample of main sequence stars with 7D measurements supplied by Gaia and
SDSS, we study the kinematic properties of the local (within∼ 10 kpc from the Sun) stellar …

Anisotropy of the Milky Way's stellar halo using K giants from LAMOST and Gaia
The anisotropy parameter β characterizes the extent to which orbits in stellar systems are
predominantly radial or tangential and is likely to constrain, for the stellar halo of the Milky …

Aurigaia: mock Gaia DR2 stellar catalogues from the auriga cosmological simulations
We present and analyse mock stellar catalogues that match the selection criteria and
observables (including uncertainties) of the Gaia satellite data release 2 (DR2). The source …
