Group Accretion in Milky Way-like Stellar Haloes
Thomas M. Callingham, Amina Helmi
As galaxies form hierarchically, larger satellites may accrete alongside smaller companions in group infall events. This coordinated accretion is likely to have left signatures in…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs
Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16
Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) -- III. Age and metallicity distribution of Gaia-Sausage-Enceladus stars near the Sun
Yllari K. González-Koda, Tomás Ruiz-Lara, Carme Gallart +14
Context. Gaia-Sausage-Enceladus is considered the last major merger that contributed to the formation of the Milky Way. Its remnants dominate the nearby accreted stellar halo of th…
Chemical characterisation of small substructures in the local stellar halo
Emma Dodd, Tadafumi Matsuno, Amina Helmi +5
The local stellar halo of the Milky Way is known to contain the debris from accreted dwarf galaxies and globular clusters, in the form of stellar streams and over-densities in the…
