General Description

• We propose to obtain X-Shooter spectra of one quasar within the
  Deep-02h VVDS Field in order to cross-correlate their Ly-$\alpha$ 1215
  \AA, CIV 1548-1550 \AA\ and MgII 2796-2803 \AA\ absorbers with the
  7972 foreground galaxies with secure spectroscopic redshifts. The
  CFHTLS-D1-02h equatorial field has been extensively observed by the
  magnitude-selected VVDS Deep spectroscopic VIMOS survey yielding
  reliable spectroscopic identifications for several thousands objects
  between z = 0 and z = 5. It is a pure I-band limited dataset for which
  the 2D spectra have been observed and redshifts accurately measured
  with spectral features such as the Lyman break, the Ly-alpha emission,
  the FUV absorption lines, etc. Spectroscopic redshifts are reliable at
  a Delta(z)=0.005 level. The selection function is well-controlled
  through the whole redshift baseline up to z~5. Here, we propose to
  make use of the UV to IR coverage of X-Shooter to look for absorbers
  in the spectra of some of the quasar in the field.
