JADES

The JWST Advanced Deep Extragalactic Survey (JADES) was the largest deep survey program undertaken during the first few years of JWST operations. Three GTO teams (NIRCam, NIRSpec, and MIRI-U.S.) combined observing time to produce a survey that will ultimately cover more than 100 square arcminutes from 0.7 to 5 microns and 10 square arcminutes at 7.7 microns, as well as obtain thousands of galaxy spectra.

The imaging data include Data Release 2 (DR2), which covers a larger area of GOODS-S and combines all JADES imaging with publicly available data in the field. The DR2 mosaics supersede those from Data Release 1 (DR1). Data Release 3 (DR3) provides the first JADES imaging mosaics of GOODS-N, covering 56 square arcminutes.

DR1 included spectra for more than 250 sources in GOODS-S; these spectra were subsequently superseded by Data Release 4 (DR4). DR2 did not include spectroscopic data. DR3 added more than 4,000 spectra, with measured redshifts for 2,375 sources. DR4 provides a full and consistent re-reduction of the NIRSpec spectroscopic sample, including spectra for more than 1,700 new sources and yielding a final sample with robust redshifts for 3,297 galaxies. DR4 spectra supersede all DR1 spectra and the majority of DR3 spectra.

DR2 and DR3 include photometric catalogs, while DR1, DR3, and DR4 include catalogs of emission-line fluxes. Photometric measurements and photometric-redshift estimates in the latest catalogs were produced using the same methodology as in 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.

Updates

10/12/26:  JADES Data Release 4 (DR4)

Re-reduction of full spectroscopic sample as well as new spectra for sources in GOODS-S and GOODS-N.  Includes catalogs (v1.2) of emission line fluxes and redshifts. DR4 spectra (v2.0) supersede all DR1 spectra and and a majority of DR3 spectra (v1.0).

05/06/24:  JADES Data Release 3 (DR3)

Mosaics (v2.0), spectra (v1.0), photometric catalog (v1.0) and spectral catalogs (v1.1) for GOODS-N, and spectra (v1.0) and new spectral catalogs (v1.1) for GOODS-S.

10/20/23:  JADES Data Release 2 (DR2)

NIRCam mosaics (v2.0) with new filters included, as well as an update to segmentation/detection maps and deep photometric catalogs (v2.0) for GOODS-S.  

06/15/23:  JADES Data Release 1 (DR1)

NIRCam mosaics, detection, and segmentation images (v1.0) and spectra (v1.0) for GOODS-S.

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.

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.

• In the MAST Search Portal, set the Provenance Name filter to JADES in an Advanced Search to find these data. A direct Portal link to JADES data is provided here as well.
• The user guide for how to search and download products using the MAST Portal is available here.
• For Astroquery, the following example code demonstrates how to search for and download these products. This code assumes that you want to download all products from this HLSP, so you may want to consider narrowing down your search for large HLSPs (> 10 GB) or those with many individual files (> 10k). You can find more astroquery.mast tutorials here.

Clear-prism spectra contain preview images. To retrieve the preview spectral images, select the observations of interest, add them to the download basket, and uncheck (Minimum Recommended Products) MRP in the Download Manager.

Catalogs are only available via the direct download links below.
