Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
Planned Impact
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

Description | We have assembled. aligned and delivered one of the world's largest wide field corrector lens assembly to the Mayall telescope in Arizona for the DESI project. The corrector was successfully commissioned in April 2019 and the full DESI instrument was commissioned in 2020/21. The main 5-year science survey was started in May 2021 and by January 2022 had catalogued over 7.5 million galaxy spectra, more than all previous 3D surveys combined. |
Exploitation Route | The DESI corrector is part of the DESI instrument that will be conducting a 5 year cosmological survey. This survey data will be available to the wider astronomical community. |
