The Universe is comprised of hundreds of billions of galaxies, each populated by hundreds of billions of stars. Astrophysics aims to understand the complexity of this almost incommensurable number of stars, stellar clusters and galaxies, including their spatial distribution, formation, and current interactions with the interstellar and intergalactic media. A considerable fraction of astrophysical discoveries require large statistical samples, which can only be addressed with multi-object spectrographs (MOS). Here we introduce the MOSAIC study of an optical/near-infrared MOS for the European Extremely Large Telescope (E-ELT), which has capabilities specified by science cases ranging from stellar physics and exoplanet studies to galaxy evolution and cosmology. Recent studies of critical technical issues such as sky-background subtraction and multi-object adaptive optics (MOAO) have demonstrated that such a MOS is feasible with current technology and techniques. In the 2020s the E-ELT will become the world’s largest optical/IR telescope, and we argue that it has to be equipped as soon as possible with a MOS. MOSAIC will provide a vast discovery space, enabled by a multiplex of ∼ 200 and spectral resolving powers of R = 5 000 and 20 000. MOSAIC will also offer the unique capability of 10-to-20 ‘high-definition’ (MOAO) integral-field units, optimised to investigate the physics of the sources of reionisation, providing the most efficient follow-up of observations with the James Webb Space Telescope (JWST). The combination of these modes will enable the study of the mass-assembly history of galaxies over cosmic time, including high-redshift dwarf galaxies and studies of the distribution of the intergalactic medium. It will also provide spectroscopy of resolved stars in external galaxies at unprecedented distances, from the outskirts of the Local Group for main-sequence stars, to a significant volume of the local Universe, including nearby galaxy clusters, for luminous red supergiants.

The VIRMOS consortium of French and Italian Institutes is manufacturing 2 wide field imaging multi-object spectrographs for the European Southern Observatory Very Large Telescope, with emphasis on the ability to carry over spectroscopic surveys of large numbers of sources. The Visible Multi-Object Spectrograph, VIMOS, is covering the 0.37 to 1 micron wavelength domain, with a full field of view of 4 by 7 by 8 arcmin² in imaging and MOS mode. The Near IR Multi-Object Spectrograph, NIRMOS, is covering the 0.9 to 1.8 microns wavelength range, with afield of view 4 by 6 by 8 arcmin² in MOS mode. The spectral resolution for both instrument scan reach up to R equals 5000 for a 0.5 arcsec wide slit. Multi-slit masks are produced by a dedicated Mask Manufacturing Machine cutting through thin Invar sheets and capable of producing 4 slit masks approximately 300 by 300 mm each with approximately slits 5.7 mm long in less than one hour. Integral field spectroscopy is made possible in VIMOS by switching in the beam specially build masks fed by 6400 fibers coming form a 54 by 54 arcsec² integral field head with a 80 by 80 array of silica micro-lenses. NIRMOS has a similar IFS unit with a field of 30 by 30 arcmin². These instruments are designed to offer very large multiplexing capabilities. In MOS mode, about 1000 objects can be observed simultaneously with VIMOS, with a S/N equals 10 obtained on galaxies with I equals 24 in one hour, and approximately 200 objects can be observed simultaneously with NIRMOS, with a S/N equals 10 obtained don galaxies with J equals 22, H equals 20.6 in 1h at R_eq equals 200. We present here the status of VIMOS, currently under final integration, with expected first light in the summer 2000, together with the final design of NIRMOS presented at the Final Design Review. The VLT-VIRMOS deep redshift survey of more with the final design of NIRMOS presented at the Final Design Review. The VLT-VIRMOS deep redshift survey of more than 150000 galaxies over the redshift range 0 < z < 5 will be undertaken based on 120 guaranteed nights awarded to the project.
