Satellite Infall and Mass Deposition on the Galactic Centre
  We model the infall of a 2e5 Msun satellite galaxy on to the inner 200 parsec
of our Galaxy, to test whether the satellite could perturb the gas previously
on stable orbits in the central molecular zone (CMZ), as proposed by Lang et
al. (2013). This process would have driven a large gas inflow around 10 Myr
ago, necessary to explain the past high accretion rate onto the super-massive
black hole, and the presence of young stars in the inner parsecs of the Galaxy.
Our hydrodynamical simulations show a much smaller inflow of gas, not
sufficient to produce the aforementioned effects.
