Early Release Science

To realize JWST’s full science potential over this timescale, the scientific community must rapidly learn to use its sophisticated capabilities. To accelerate the process of discovery by the community, and maximize the science productivity of the mission, STScI, in consultation with the JWST Advisory Committee, has developed the Director’s Discretionary Early Release Science (DD-ERS) program. DD-ERS proposals will be reviewed, selected, and publicized prior to the Cycle 1 GO deadline, and Archival Research proposals based on DD-ERS observations will be permitted beginning in Cycle 1. To enable STScI to prepare for the proposal review, Notices of Intent (NoI) to propose for the DD-ERS program were due on March 3, 2017 at 8:00 PM ET. The final ERS Proposals are due on August 18, 2017, 8:00 PM ET. Further proposals will be still received six months later. The overall goals of the DD ERS program are to ensure open access to representative datasets in support of the preparation of Cycle 2 proposals, as well as to ensure a broad cross-section of the astronomical community in familiarizing themselves with JWST data and scientific capabilities. The STScI Director will make up to 500 hours of discretionary time available for ERS, and resources are allocated to support up to 15 teams.

200 Notices of Intent to propose were received with a total of 3,665 investigators/collaborators, or an average of 18 scientists per team. There were 2,379 unique investigators/collaborators, including 477 who have never proposed for time on Hubble. The largest team is comprised of 119 investigators. Principal Investigators (PIs) and Co-Principal Investigators (CoPIs) are based in 24 countries, with representation from 34 U.S. states and 1 U.S. territory.

A broad representation of submissions in different science areas covering the four JWST science themes, has been received. Topics covered are as shown below.

    Je pense qu’il s’agissait de la répétition de « détails »? C’est corrigé!
