The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

We review the recent theoretical and observational developments concerning the interaction
of the Large Magellanic Cloud (LMC) with the Milky Way and its neighbourhood. An …

Context. The second Gaia data release (Gaia DR2) contains high-precision positions,
parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for …

Gravitational interactions between the Large Magellanic Cloud (LMC) and the stellar and
dark matter halo of the Milky Way are expected to give rise to disequilibrium phenomena in …

We analyse an N-body simulation of the interaction of the Milky Way (MW) with a Sagittarius-
like dSph (Sgr), looking for signatures which may be attributed to its orbital history in the …

Aims. We perform a comprehensive determination of the systemic proper motions of 74
dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data …

We use the second data releases of the European Space Agency Gaia astrometric survey
and the high-resolution Galactic Archaeology with HERMES (GALAH) spectroscopic survey …

Stellar streams are excellent probes of the underlying gravitational potential in which they
evolve. In this work, we fit dynamical models to five streams in the Southern Galactic …

We present N-body simulations of a Sagittarius (Sgr)-like dwarf spheroidal galaxy that
follows its orbit about the Milky Way (MW) since its first crossing of the Galaxy's virial radius …

Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical
heating and phase-mixing in their disks. Such features have also been observed in our own …
