JADES: James Webb Space Telescope Infrared Imaging and Spectroscopy Survey

JADES is an infrared imaging and multi-object spectroscopy survey focused on two deep fields: the Hubble Deep Field (GOODS-N) and Hubble Ultra Deep Field (GOODS-S). The survey conducted NIRCam imaging in 8-10 bands, covering about 42 square arcminutes to very deep limits and another 167 square arcminutes to a typical exposure time of 25 hours, and performed NIRSpec spectroscopy on over 5000 targets. The dataset is produced by the Space Telescope Science Institute and is subject to a CC By 4.0 license.

Use Cases

• Detect and classify high-redshift galaxies based on deep infrared imaging.
• Analyze galaxy spectra for chemical composition and redshift measurements based on multi-object spectroscopy.
• Study early universe galaxy formation using data from the Hubble Deep and Ultra Deep Fields.
• Train machine learning models for astronomical object detection in multi-band infrared images.

Strengths

• Imaging covers about 42 square arcminutes to very deep limits (fainter than 30th magnitude) with an average of about 100 hours of total exposure time.
• Spectroscopy includes over 5000 targets on 31 separate pointings, with deep exposures of 55 hours spread across 5 dispersers.
• Coordinated parallels with the MIRI instrument extend imaging further into the infrared.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment.
