Published purpose

The project will combine U-band imaging from the Canada-France-Hawaii Telescope (CFHT) with Euclid, Subaru, and Spitzer data in the Euclid Deep Field North to produce photometric catalogs of millions of galaxies over an unprecedented combination of area (10 sq deg) and depth (27 mag). The U-band data we will add to this dataset is key for accurate photometric redshifts and measuring rates of star formation in galaxies. The joint catalogs will open a large field of science areas for investigation; in particular, the team will study how the fates of millions of galaxies are governed by their locations within the filamentary, Universe-pervading Cosmic Web. The catalogs will contain millions of galaxies and will be made public enabling a vast array of research and a legacy treasure-trove.
