The GALAH Survey and Galactic Archaeology in the next decade
  The field of Galactic Archaeology aims to understand the origins and
evolution of the stellar populations in the Milky Way, as a way to understand
galaxy formation and evolution in general. The GALAH (Galactic Archaeology with
HERMES) Survey is an ambitious Australian-led project to explore the Galactic
history of star formation, chemical evolution, minor mergers and stellar
migration. GALAH is using the HERMES spectrograph, a novel, highly multiplexed,
four-channel high-resolution optical spectrograph, to collect high-quality R ~
28,000 spectra for one million stars in the Milky Way. From these data we will
determine stellar parameters, radial velocities and abundances for up to 29
elements per star, and carry out a thorough chemical tagging study of the
nearby Galaxy. There are clear complementarities between GALAH and other
ongoing and planned Galactic Archaeology surveys, and also with ancillary
stellar data collected by of major cosmological surveys. Combined, these data
sets will provide a revolutionary view of the structure and history of the
Milky Way.
