The Euclid/WFIRST Spitzer Legacy Survey Program Capak_spitzer-proposal Euclid Thu, Oct 13, 2016

The Euclid/WFIRST Spitzer Legacy Survey proposal has been selected for observations in Spitzer GO Cycle 13. The PI is Dr. Peter Capak from IPAC, Caltech, leading an international team of 51 Co-Is. This ambitious program has been awarded 5286 hours of Spitzer Legacy Science Time, the most time awarded in this cycle, and a substantial fraction of the total available time in the remainder of currently planned mission lifetime for Spitzer. This program will observe 20 square degrees to 2h per pointing split between the Chandra Deep Field South (CDFS) and the North Ecliptic Pole (NEP). This will achieve 5sigma depths of 24.6 AB mag. It will enable the scientific research on reionization in the Universe, stellar mass from 3<z<10 and luminous quasars.
