Projects for the topic redshift

Current projects

The Dark Energy Spectroscopic Instrument in a new multi-object spectrograph being built for the Mayall telescope, which will be able undertake a spectroscopic survey 20 times faster than the Sloan Telescope, used for the influential Sloan Digital Sky Survey. It will be used to create a galaxy survey containing 30 million galaxies forming an unprecedented large-scale structure survey, which will be cosmic variance limited out to redshift z<1.4. Percival is one of the working group chairs for this survey and a member of the DESI executive.

The extended Baryon Oscillation Spectroscopic Survey is an ongoing survey using the Sloan telescope. It is the only ongoing cosmological galaxy redshift survey and has already published a number of cosmological measurements covering the intermediate redshift range
0.9<z<2.0. 

Proposed projects

In 2022 the European Space Agency will launch the Euclid satellite mission. Euclid is a medium class astronomy and astrophysics space mission that will undertake a galaxy redshift survey over the redshift range 0.9 < z < 1.8, while simultaneously performing an imaging survey in both visible and near infrared bands. The complete survey will provide hundreds of thousands of images and several tens of Petabytes of data.
