Project Details


BigBOSS is a ground-based dark energy experiment to study the cosmological expansion rate and the growth of structure with a wide-angle spectroscopic galaxy and quasar redshift survey. A wide range of additional science is possible using the 5000 fibre multi-object spectrograph required for this experiment, including studying galaxy formation and evolution, galaxy cluster surveys, the structure of the Milky-Way galaxy and Galactic archeology.

In order to undertake the proposed survey, a US-Europe-China collaboration has come together with the aim of constructing a 5000-fiber spectrograph that will initially deploy on the Mayall 4m-telescope. The key science goals represent a field in which the UK has world leadership and strong scientific interest, built up through STFC support for participation in the 2-degree Field Galaxy Redshift Survey and the Dark Energy Survey.

This grant provides development funding for two key areas of hardware development where the UK has internationally regarded expertise - the optical corrector, and the fibre system, and will retain UK involvement in this ground-breaking project.
