Title: Euclid: an ESA Mission with NASA Involvement to Study the Dark Universe
Abstract: Euclid is a European Space Agency mission with NASA involvement to study the geometry and nature of the dark universe. It is optimized for two of the primary probes of dark energy: weak gravitational lensing and galaxy clustering. Euclid launched on 1 July 2023 on a SpaceX Falcon 9 from Cape Canaveral. During its 6 year primary mission, Euclid will survey over 13,000 sq.deg. of extragalactic sky and obtain optical images (530-920nm band), near-infrared images (Y,J,H) and slitless near-infrared grism spectra (1206nm-1892nm, R~480). All Euclid data will be made public to the world community after a proprietary period. Euclid’s first large data set of over 60 square degrees was released on March 19, 2025 (Quick Release 1 or Q1), and the first year of data (about 2000 square degrees) will be released in 2026. I will give an overview of Euclid’s science goals, observing status, and the Q1 data and results.
