Description
The Gaia mission will have a profound impact on our understanding of
the structure and dynamics of the Milky Way. Gaia is providing an
exhaustive census of stellar parallaxes, proper motions, positions,
colors and radial velocities, but also leaves some glaring holes in an
otherwise complete data set. The radial velocities measured with the
on-board high-resolution spectrograph will only reach some 10 % of the
full sample of stars with astrometry and photometry from the mission,
and detailed chemical information will be obtained for less than 1 %.
Teams all over the world are organizing large-scale projects to provide
complementary radial velocities and chemistry, since this can now be
done very efficiently from the ground thanks to large and mid-size
telescopes with a wide field-of-view and multi-object spectrographs. As
a result, automated data processing is taking an ever increasing
relevance, and the concept is applying to many more areas, from
targeting to analysis. In this paper, I provide a quick overview of
recent, ongoing, and upcoming spectroscopic surveys, and the strategies
adopted in their automated analysis pipelines.
