    From ESO: “The Antennae Galaxies – NGC4038/9” 


    European Southern Observatory

    One of the first images from the new VIMOS facility, obtained right after the moment of “first light” on February 26, 2002. It shows the famous “Antennae Galaxies” (NGC 4038/9), the result of a recent collision between two galaxies.

    VIMOS
    VIMOS is a visible (360 to 1000 nm) wide field imager and multi- object spectrograph mounted on the Nasmyth focus B of UT3 Melipal. The instrument is made of four identical arms with each a field of view of 7′ x 8′ with a 0.205″ pixel size and a gap between each quadrant of ~2′. Each arm is equipped with 6 grisms providing a spectral resolution range from ~200-2500 and with one EEV CCD 4k x 2k.

    VIMOS operates in three different modes: Imaging (IMG), Multi-Object Spectroscopy (MOS), and with Integral Field Unit (IFU).

    As an immediate outcome of this dramatic event, stars are born within massive complexes that appear blue in this composite photo, based on exposures through green, orange and red optical filters.

    Individual exposures of 60 seconds each; image quality 0.6 arcsec FWHM; the field measures 3.5 x 3.5 arcmin2. North is up and East is left.

    From ESO: “Huge Map of the Distant Universe Reaches Halfway Point” 

    12 March 2013

    VLT survey charts positions of 55,000 galaxies

    The largest project ever undertaken to map out the Universe in three dimensions using ESO telescopes has reached the halfway stage. An international team of astronomers has used the VIMOS instrument on the ESO Very Large Telescope to measure the distances to 55000 galaxies as part of the VIPERS survey . This has already allowed them to create a remarkable three-dimensional view of how galaxies were distributed in space in the younger Universe. This reveals the complex web of the large-scale structure of the Universe in great detail.

    By studying the cosmic web astronomers can test theories of how the Universe formed and evolved and help to track down the properties of the mysterious dark energy that is making the expansion of the Universe speed up. By mapping how large-scale structure grows with time they can also check whether Einstein’s theory of general relativity holds precisely, or whether it may need to be revised.

    The light of each galaxy is spread out into its component colours within VIMOS. Subsequent careful analysis then allows astronomers to work out how fast the galaxy appears to move away from us — its redshift. This in turn reveals its distance and, when combined with its position on the sky, its location in the Universe.”
