Query: From Detailed Galaxy Simulations to a Realistic End-of-Mission Gaia
  Catalogue   We address the problem of identifying remnants of satellite galaxies in the
halo of our galaxy with Gaia data. We make use of N-body simulations of dwarf
galaxies being disrupted in the halo of our galaxy combined with a Monte Carlo
model of the Milky Way galaxy. The models are converted to a simulated Gaia
catalogue containing a realistic number ($\sim10^8$--$10^9$) of stars. The
simulated catalogue can be used to study how to handle the large data set that
Gaia will provide and to study issues such as how to best retrieve information
on substructure in the Galactic halo. The techniques described are applicable
to any set of N-body simulations of (parts of) the Galaxy.
