| Abstract: |
HERMES is a multi-fibre spectrograph being built for the AAT 3.9m
telescope, designed to simultaneously obtain high resolution
(R ∼ 28000) spectra for ∼ 400 stars over a 2° field of
view. The Galactic Archaeology with HERMES (GALAH) Survey is a major
Australian-led project to obtain detailed elemental abundances for a
million stars, with the goal of using chemical tagging to decipher the
formation history of the Milky Way. For the GALAH Survey, ∼106
stars (down to V∼14, at S/N ∼100 / resolution element) will
be observed in four passbands, selected to include elements from all
major independently-varying element groups, thus allowing direct
determination of abundances for each star. The survey will also be
directly complementary to wide-area photometric surveys such as
Skymapper, and the multidimensional dataset which will come from ESA's
Gaia mission. |
