First VIMOS spectra of faint galaxies

Some of the first spectra of distant galaxies obtained with VIMOS in Multi-Object-Spectroscopy (MOS) mode. More than 220 galaxies were observed simultaneously, an unprecedented efficiency for such a "deep" exposure, reaching so far out in space.

These spectra allow to obtain the redshift, a measure of distance, as well as to assess the physical status of the gas and stars in each of these galaxies. A part of this photo is enlarged as ESO Press Photo eso0209n

MOS-spectra obtained with two quadrants totaling 221 slits + 6 reference objects (stars placed in square holes to ensure a correct alignment). Exposure time 900 seconds; LR(red) grism. This is the raw (unprocessed) image of the spectra.
