Community Astrophysics with WFIRST: Guest Observer and Archival Science Wfirstpicture Euclid Mon, Nov 16, 2015

The Wide Field Infrared Survey Telescope (WFIRST) is a NASA mission currently under study for the next decade whose primary objectives are to study the nature of dark energy, via gravitational lensing, supernovae and baryon acoustic oscillations, and search for and characterize exoplanets, via microlensing and coronagraphy. This international meeting, "Community Astrophysics with WFIRST: Guest Observer and Archival Science", to be held in Pasadena from 29 Feb. through 2 March 2016, will focus on the GO and GI components of the WFIRST mission, bringing together experts in the community to discuss groundbreaking science that can be done with the GO and archival opportunities of WFIRST. Due to the synergy between WFIRST and Euclid, this meeting is of great interest to the Euclid community.
