DESI: The Dark Energy Spectroscopic Instrument

  • Percival, Will (PI)

Project Details


We request support here for £0.5M (at the 100% funding level) which will be used to allow scientists at the University of Portsmouth to join the DESI collaboration, as part of the overall UK buy-in to the project.

DESI is a ground-based experiment to study the expansion rate of the universe and the growth of cosmological structure with a wide-angle spectroscopic galaxy and quasar redshift survey. The 5000-fibre DESI spectrograph will allow an order of magnitude improvement in the distance scale over the redshifts 0.8
