Query: The Gaia-ESO Survey: a quiescent Milky Way with no significant
  dark/stellar accreted disc   According to our current cosmological model, galaxies like the Milky Way are
expected to experience many mergers over their lifetimes. The most massive of
the merging galaxies will be dragged towards the disc-plane, depositing stars
and dark matter into an accreted disc structure. In this work, we utilize the
chemo-dynamical template developed in Ruchti et al. to hunt for accreted stars.
We apply the template to a sample of 4,675 stars in the third internal data
release from the Gaia-ESO Spectroscopic Survey. We find a significant component
of accreted halo stars, but find no evidence of an accreted disc component.
This suggests that the Milky Way has had a rather quiescent merger history
since its disc formed some 8-10 billion years ago and therefore possesses no
significant dark matter disc.
