TL;DR
GALATEA is a proposed 15-meter spectroscopic survey facility designed to perform wide-field, multi-object spectroscopy of stars in the Milky Way and Local Group, enabling detailed chemical and kinematic studies beyond current capabilities.
Contribution
It introduces a novel 15-meter, wide-field, high-multiplex spectroscopic instrument that significantly enhances survey power and coverage compared to existing facilities.
Findings
Enables deep, chemically detailed spectroscopy of vast stellar samples.
Provides precise radial velocities and chemical abundances with Gaia data integration.
Offers an order-of-magnitude increase in survey efficiency over current instruments.
Abstract
\textsc{GALATEA} (the \emph{Galactic Archaeology and Local-group Astrophysics Telescope for Extended Areas}) is a concept for a dedicated 15-m, wide-field, 10,000-fibre spectroscopic survey facility in the northern hemisphere, optimized for degree-scale, multi-object spectroscopy. With a corrected field-of-view and both medium- (--) and high-resolution (--) modes, \textsc{GALATEA} would open a new regime in Galactic and Local Group astronomy: deep, chemically detailed spectroscopy of vast samples of individual stars in the outer disc, warp, flare, halo substructures, M31, M33 and their dwarf satellites, far beyond the reach of current surveys. By delivering precise radial velocities and detailed chemical abundances for stars with exquisite astrometry and photometry from \emph{Gaia} and its proposed…
