VIPERS: clustering of galaxies and dark matter at redshift 1

Our model for dark matter is incredibly successful despite its simplicity.  But things get complicated when we try to understand galaxies, and actually the entire baryonic component of the Universe poses significant problems for theories of structure formation.  A step forward in understanding how galaxies relate to...

VIPERS: halfway to measuring 100,000 galaxy spectra

The VIPERS project is mapping the distribution of galaxies in the distant Universe. It uses the VIMOS spectrograph on the European Southern Observatory Very Large Telescope (ESO VLT) in Chile. By fall 2014, the programme will have measured nearly 100,000 galaxy spectra, each with a precise redshift measurement.
