In July 2023, 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. About 10 billion sources will be observed by Euclid out of which several tens of million galaxy redshifts will be measured and used to make galaxy clustering measurements. These observations will be used to help to understand Dark Energy, the physical mechanism causing the current acceleration in the expansion of the Universe.
Within the Euclid consortium, Mike Hudson serves as the Canadian Euclid Consortium Board representative, and Will Percival serves as a co-lead of the Galaxy Clustering science working group, and is one of four Science Coordinators for the consortium, with various other roles. Together with Euclid Consortium members Michael Balogh, and James Taylor and two WCA Euclid Fellows (arriving fall 2023) they ensure that the WCA remains at the heart of the Euclid science.
