Published purpose

Galaxy Surveys are a key resource for observational cosmology, with the potential to provide the answers to many fundamental questions in modern physics. The ESA-led Euclid mission, scheduled for launch early in 2023, will provide a survey an order of magnitude larger than current galaxy surveys and with far lower levels of systematic problems thanks to its space-based observations. This grant is designed to exploit key leadership positions held by the PI within Euclid, to help to measure the cosmological expansion rate between redshifts 0.9 and 1.9, testing Dark Energy. Complementary structure growth measurements will test Einstein’s theory of Gravity on the largest scales possible. The scale-dependence of the clustering signal will be used to measure the masses of neutrinos through their early Universe effects, and to set constraints on the evolution of galaxies and structure over cosmological time-scales. This grant will enable a group of early-career researchers to work at the heart of the Euclid Consortium. Furthermore, it will train these scientists with the key skills required for a number of future career directions.
