JADES

The JWST Advanced Deep Survey (JADES) is the largest deep survey program that will be executed in the first few of years of operation of JWST.  Three GTO Teams (NIRCam, NIRSpec, MIRI-U.S.) have combined time to produce a survey which will ultimately cover over 100 square arc minutes from 0.7 to 5 microns and 10 square arc minutes at 7.7 microns and produce thousands of galaxy spectra.  The imaging data presented now includes DR2 which covers a larger area of GOODS-S and also co-adds images from all JADES and publicly available data for the area.  DR2 mosaics supersede those from DR1.  DR3 imaging presents mosaics of GOODS-N covering 56 square arc minutes for the first time.  DR1 included spectra for over 250 sources in GOODS-S.  DR2 did not include any spectra.  DR3 presents over 4000 additional spectra with 2375 sources with measured redshifts.  DR2 and DR3 include photometric catalogs and DR1 and  DR3 also include catalogs of emission line fluxes.  Photometric measurements and photo-z estimations presented in the latest catalogs were produced in the same fashion as for the first data release.

Additionally, "FITSMap" provides a multicolor images browser and links to the photometry.  FITSMap is also accessible directly for the GOODS-S and GOODS-N fields.

Figure 1 shows the footprint for this Data Release 2 while Figure 2 shows the footprint for GOODS-N, part of Data Release 3.

In addition to increasing the areal coverage, the production of mosaics was modified to permit co-addition of all images in a given filter covering an area. Photometric measurements and photo-z estimations were done in the same fashion as for the first data release.

Figure 3 shows an example of a galaxy with a photometric redshift of 1.78 that is nearly invisible to HST ACS but is seen as a well-resolved but obscured spiral to JWST. 

The NIRSpec spectra presented as part of this release comprise a sample selected largely from objects detected using HST imaging of the ultra deep field (UDF). Bunker et al. 2023 describes the process of prioritizing objects to be placed on slits. About 250 galaxies were targeted using the 0.6 to 5.3 micron prism with up to 28 hours of exposure. Most of these objects were also targeted using all three R~1000 gratings and the longest wavelength R~2700 grating with up to 7 hours of exposure.

Figure 4 includes sample R~100 Clear/Prism spectra from the first data release (Bunker et al. 2023). Figure 5 displays an example preview image for a Clear/Prism spectrum.

Update 05/06/24:  JADES Data Release 3 - Mosaics, catalogs, and spectra for GOODS-N, and new catalogs and spectra for GOODS-S.

Update 10/20/23:  JADES Data Release 2 - NIRCam mosaics of GOODS-S with new filters included, as well as an update to segmentation/detection maps and photometric catalogs.

Update 06/15/23:  NIRCam detection and segmentation images added to JADES Data Release 1.

JADES images and spectra are available in the MAST Portal (web-based, cross-mission search interface) and Astroquery (Python package to search for and download files from Python scripts you write), and via the direct download table below. Set the Provenance Name filter to JADES in the Portal Advanced Search to find all or individual images. Clear-prism spectra contain preview images as minimum recommended products (MRP). To retrieve the preview spectral images, select the observations of interest, add them to the download basket, and uncheck MRP in the Download Manager. Catalogs are only available via the direct download links below.
