ABSTRACT The Milky Way halo is one of the few galactic haloes that provides a unique
insight into galaxy formation by resolved stellar populations. Here, we present a catalogue …

Context. The Gaia mission has provided the largest ever astrometric chart of the Milky Way.
Using it to map the Galactic halo is helpful for disentangling its merger history. Aims. The …

In the Gaia era, stellar kinematics are extensively used to study Galactic halo stellar
populations, to search for halo structures, and to characterize the interface between the halo …

We present a panoramic map of the stellar streams of the Milky Way based upon astrometric
and photometric measurements from the Gaia DR2 catalogue. In this first contribution, we …

We have compiled a new sample of 240 halo objects with accurate distance and radial
velocity measurements, including globular clusters, satellite galaxies, field blue horizontal …

We combine Gaia data release 1 astrometry with Sloan Digital Sky Survey (SDSS) images
taken some∼ 10–15 years earlier, to measure proper motions of stars in the halo of our …

The first and second moments of stellar velocities encode important information about the
formation history of the Galactic halo. However, due to the lack of tangential motion and …

Aims. We study the dynamical properties of halo stars located in the solar neighbourhood.
Our goal is to explore how the properties of the halo depend on the selection criteria used to …

Context. The Gaia mission has provided the largest catalogue ever of sources with
tangential velocity information. However, it is difficult to use this catalogue for dynamical …

The velocity distribution of stars is a sensitive probe of the gravitational potential of the
Galaxy, and hence of its dark matter distribution. In particular, the shape of the dark halo (eg …
