", "abstract": "This report describes the 2014 study by the Science Definition Team (SDT) of the Wide-Field Infrared Survey Telescope (WFIRST) mission. It is a space observatory that will address the most compelling scientific problems in dark energy, exoplanets and general astrophysics using a 2.4-m telescope with a wide-field infrared instrument and an optical coronagraph. The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope as its top priority for a new large space mission. As conceived by the decadal survey,\nWFIRST would carry out a dark energy science program, a microlensing program to\ndetermine the demographics of exoplanets, and a general observing program\nutilizing its ultra wide field. In October 2012, NASA chartered a Science\nDefinition Team (SDT) to produce, in collaboration with the WFIRST Study Office\nat GSFC and the Program Office at JPL, a Design Reference Mission (DRM) for an\nimplementation of WFIRST using one of the 2.4-m, Hubble-quality telescope\nassemblies recently made available to NASA. This DRM builds on the work of the\nearlier WFIRST SDT, reported by Green et al. (2012) and the previous WFIRST-2.4\nDRM, reported by Spergel et. (2013). The 2.4-m primary mirror enables a mission\nwith greater sensitivity and higher angular resolution than the 1.3-m and 1.1-m\ndesigns considered previously, increasing both the science return of the\nprimary surveys and the capabilities of WFIRST as a Guest Observer facility.\nThe addition of an on-axis coronagraphic instrument to the baseline design\nenables imaging and spectroscopic studies of planets around nearby stars.", "date": "2017-06-30", "date_type": "published", "publisher": "arXiv", "id_number": "CaltechAUTHORS:20170629-130428473", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170629-130428473", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "COSMOS" }, { "id": "SPLASH" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "corp_creators": { "items": [ "WFIRST Study Office", "Science Definition Team" ] }, "doi": "10.48550/arXiv.1503.03757", "primary_object": { "basename": "1503.03757.pdf", "url": "https://authors.library.caltech.edu/records/hnsv3-9d647/files/1503.03757.pdf" }, "resource_type": "monograph", "pub_year": "2017", "author_list": "Spergel, D.; Gehrels, N.; et el." } ]
