“4MOST: the 4-metre Multi-Object Spectroscopic Telescope”

prof. dr hab. Boud Roukema (Institute of Astronomy, Nicolaus Copernicus University)

Abstract:
4MOST — the 4-m Multi-Object Spectroscopy Telescope project is an astronomical survey instrument that is currently undergoing commissioning on the ESO VISTA telescope at Paranal. With 2436 optical fibres and a 4.2 square degree field of view, 4MOST will carry out simultaneous stellar spectroscopic surveys of the Milky Way and extragalactic redshift surveys covering substantial fractions of the past light cone. 4MOST expects to obtain spectra for 25 million objects over 15000 square degrees during the first 5-year period. This includes 10 4MOST Consortium Surveys (70% of the observing time ) and 15 Community Surveys (30% of the observing time). An overview of the instrument and the galactic (Milky Way halo, bulge, and disk; Magellanic Clouds) and extragalactic (galaxy clusters, AGNs, galaxy evolution, cosmological redshifts, time-variable objects) surveys will be presented.
