About the Survey
The Cosmic Dawn Survey (DAWN) is a Euclid Key Project (KP) within the Primeval Universe (PU) and Galaxy Evolution (GAE) Science Working Groups (SWG). DAWN is creating value added catalogs for the Euclid Deep and Auxiliary Fields. It combines deep ground-based UV-optical and Sptitzer IRAC (3-5 μm) with the Euclid data in the fields. The main goals of the survey are as follows:
- Deliver photometry and redshifts for 50 million galaxies
- Measure stellar mass to z ~ 10 and UV luminosities at z = 3-12
- Identify rare massive galaxies in the early Universe
- Study the sites of reionization
- Quantify the relationship between galaxies and their dark matter halos
The DAWN image data can viewed here.
Catalogues are accesible for Euclid Consortium members through CosmoHub.
