DATA Release: Early Release Observations of SMACS0723

Oct 27, 2022

In July 2022, JWST has observed the lensing cluster SMACS0723 as part of the Early Release Observations (ERO). The prgram (PID 2736) cosists of deep multi-band imaging with NIRCam and MIRI, slitless spectroscopy with NIRISS, and multi-object spectroscopy with NIRSpec. We announce the first data release of the reduced and calibrated NIRCam mosaics in 6 bands, including PSF-matched products and ICL-corrected versions. The mosaics and the readme file can be retrieved following this link: SMACS0723 NIRCam Data Release .

sf2a 2022: Activities around the JWST - Extragalactic Deep Legacy Fields

March 17, 2022

During the sf2a meeting, which will take place in Besancon from June 07 to 10, a special session S17 will be dedicated to two of the major science cases of JWST: first Light and Assembly of Galaxies. The main goal of the meeting is to present the current landscape of observing programs, their scientific goals, and to discuss the community needs in terms of scientific products and prospects for GO Cycle 2. More information can be found on the sf2a website . Abstract subimission for oral contributions and ePosters is open until March 31st.

Organisers: H. Atek (IAP), L. Tresse (LAM), B. Magnelli (AIM), M. Trebitsch (U. Groningen), L. Ciesla (LAM), J. Blaizot (CRAL), J. Richard (CRAL)

JWST is on its way to L2 point !

Dec 26, 2021

On December 25th, the European Ariane 5 rocket succefully launched the long-awaited JWST (re-watch the live coverage here). JWST must now undergo a series of critical deployments on its way to the L2 point, which will take 29 days and 1.5 million kms. You can follow the live position of the telescope and the deployment steps here: Where is Webb ?

JWST Undergoes Final Tests in French Guiana

Nov 3, 2021

December 18th 2021 is now the official target launch date for the JWST. The telescope has arrived at the European spaceport in French Guiana where it is scheduled to board the Ariane 5 rocket later in December. It is currently going through a series of tests in the clean room of the Guiana Space Center and enginneers will soon proceed to loading its thrusters with fuel. The long journey that awaits the JWST after launch is desribed here: The Road to Launch and Beyond

NASA Leadership Assessing Mission Impacts of Coronavirus

March 24, 2020

NASA has announced that The James Webb Space Telescope team is suspending integration and testing operations. Decisions could be adjusted as the situation continues to unfold over the weekend and into next week. The decision was made to ensure the safety of the workforce. The observatory remains safe in its cleanroom environment. For more information: Nasa-leadership-assessing-mission-impacts-of-coronavirus.

Last week, STScI announced that the JWST Cycle 1 deadline was delayed to no earlier than May 27, 2020 and with an update on April 15, 2020: The-jwst-cycle-1-deadline-has-been-delayed.

Call for JWST GO Cycle 1 Proposals is now Open

January 24, 2020

The call for JWST cycle 1 proposals has been released on January 23 and submissions will be accepted through May 1, 2020. The official version of APT for cycle 1 submissions will be released on March 5. In the meantime, proposers can use the current version of APT v2020.1.1.

JWST Master Class Workshop

November 25, 2019

The call for proposals for the first Cycle of GO observations with JWST will open in January 2020, with an expected deadline in May 2020. The SNO, in collaboration with other partners, is organizing a workshop to prepare the community for the proposal submission process and the use of JWST tools. This event is part of a series of JWST wokshops organized across Europe and coordinated by ESA (cf. the list of workshops here ). The workshop will be held on February 24-25 2020 at the Institut d'Astrophysique de Paris. For more information about the program and the registration, please visit the Workshop website.

SNO Survey

May 10, 2019

In the framework of the SNO, we are collecting the scientific priorities and needs of the community in terms of proposal preparation for the first cycle of JWST observations. Also, we would like to assess the number of potential participants of a workshop that will be organized to help the community in using observations planning and proposal preparation tools. The survey will take only 2 minutes. The deadline to submit your answers is June 15.
