Subproject A9: Definition and Preparation of the 4MOST Galactic Surveys
Andreas Quirrenbach (LSW), Eva K. Grebel (ARI), Norbert Christlieb (LSW)
The 4-meter Multi-Object Spectroscopic Telescope (4MOST) is a major new facility under development for ESO with strong involvement of LSW and ARI. 4MOST is planned to collect high-quality spectra of over 40 million stars and 40 million galaxies at a resolution R > 5,000, and of 5 million stars at R ~ 20,000. Starting in 2020, 4MOST will deploy 2,436 optical fibers in a 4.1 deg2 field of view to survey the whole Southern sky. In the first funding period, we were invited to join the 4MOST project and to contribute to the definition of science goals and technical requirements (work done in subproject A5). Following the recent selection of 4MOST by ESO, we intend to prepare the 4MOST surveys of the Galactic halo and bulge by refining their scientific goals and survey strategies, compiling a target data base and developing automated data reduction pipelines for the quantitative analysis of stellar spectra from raw data to derived information such as abundances.
