ASD Colloquium Series



"The Euclid Mission"
Daniel Stern

Euclid is an ESA M-class mission with significant NASA participation designed to study the geometry and nature of the dark universe. Currently scheduled for launch in late 2020, the mission has been optimized for measurement of two primary probes of Dark Energy: (1) weak gravitational lensing, and (2) galaxy clustering, including both baryonic acoustic oscillations and redshift space distortions. By making sensitive imaging and spectroscopic measurements over 15,000 deg2 of extragalactic sky, significant ancillary science is also eagerly anticipated. Euclid will consist of a 1.2-meter space telescope with two instruments: a wide-field optical camera for imaging, and a wide-field near-infrared camera for both imaging and spectroscopy. The optical camera takes advantage of the high resolution afforded by space to make very accurate measurements of galaxy shapes, while the near-infrared camera takes advantage of the very low background in orbit to make precise measurements of galaxy fluxes and accurately measure the distances to millions of galaxies. I will discuss the current status of the Euclid mission, with an emphasis on the primary efforts of the NASA-funded US members of the Euclid Consortium. I will also discuss Euclid in the context of WFIRST, both in terms of mission design, and for lesson's learned.
