MOONS: the Multi-Object Optical and Near-infrared Spectrograph for the VLT

Abstract: MOONS is a new conceptual design for a Multi-Object Optical and Near-infrared Spectrograph for the Very Large Telescope (VLT), selected by ESO for a Phase A study. The baseline design consists of ~1000 fibers deployable over a field of view of ~500 square arcmin, the largest patrol field offered by the Nasmyth focus at the VLT. The total wavelength coverage is 0.8µm-1.8µm and two resolution modes: medium resolution and high resolution. In the medium resolution mode (R~4,000-6,000) the entire wavelength range 0… Show more

“…Future large scale spectrographs on 8 meter class telescopes (MOONS 6 ; Cirasuolo et al 2014;Cirasuolo & MOONS Consortium 2016, PFS 7 ;Sugai et al 2015) or space missions (WFIRST 8 ; Spergel et al 2013, 2015, andEuclid 9 ;Laureijs et al 2011, the deep survey for the latter) will extend the current analysis at higher redshift (z 1) with similar samplings, allowing to explore the role of the environment near the peak of the cosmic star formation history, an epoch where the connectivity between the LSS and galaxies is expected to be even tighter, with ubiquitous cold streams. Tomography of the Lyman-α forest with PFS, MOONS, ELT-HARMONI (Thatte et al 2010) tracing the intergalactic medium will make the study of the link between galaxies and this large scale gas reservoir possible (Laigle et al in prep.).…”

“…MOONS (Cirasuolo et al 2014) is a future multi-object spectrograph proposed for the VLT that, given its spectral coverage, can be used to find Lyα emitters at z = 5.7 and beyond. Its wavelength resolution, ∆λ = 0.9 Å at the Lyα observed wavelength, translates into a line-of-sight comoving resolution at z = 5.7 of ∆r z = 0.24h −1 Mpc.…”

“…APOGEE/APOGEE-2 is the only large-scale (>1,000,000 spectra for >450,000 objects) near-IR spectroscopic survey of stars, ensuring it has a unique view of all parts of our Galaxy, unhampered by interstellar obscuration in the Galactic plane. Most stellar surveys of equivalent scale-including those that have concluded (e.g., RAVE, SEGUE-1 and −2, and ARGOS; Steinmetz et al 2006, Yanny et al 2009, Freeman et al 2013, are currently underway (e.g., LAMOST, Gaia-ESO, GALAH, and Gaia; Cui et al 2012, Gilmore et al 2012, Zucker et al 2012, Perryman et al 2001, or are anticipated in the future (e.g., WEAVE, 4MOST, and MOONS; Dalton et al 2014, de Jong et al 2014, Cirasuolo et al 2014)-have been or will be performed in the optical and/or with largely medium spectral resolution (however, we note plans for highresolution modes for some of these). All of these projects provide complementary data in the form of different wavelength or spatial regimes providing essential contributions to the ongoing census of the Milky Way's stars.…”
