Arxiv: The JADES Origins Field: A New JWST Deep Field in the JADES Second NIRCam Data Release Published: 10/19/2023 12:36:32 AM Updated: 10/19/2023 12:36:32 AM

Paper abstract: We summarize the properties and initial data release of the JADES OriginsField (JOF), which will soon be the deepest imaging field yet observed with theJames Webb Space Telescope (JWST). This field falls within the GOODS-S regionabout 8' south-west of the Hubble Ultra Deep Field (HUDF), where it was formedinitially in Cycle 1 as a parallel field of HUDF spectroscopic observationswithin the JWST Advanced Deep Extragalactic Survey (JADES). This imaging willbe greatly extended in Cycle 2 program 3215, which will observe the JOF for 5days in six medium-band filters, seeking robust candidates for z>15 galaxies.This program will also include ultra-deep parallel NIRSpec spectroscopy (up to104 hours on-source, summing over the dispersion modes) on the HUDF. Cycle 3observations from program 4540 will add 20 hours of NIRCam slitlessspectroscopy to the JOF. With these three campaigns, the JOF will be observedfor 380 open-shutter hours with NIRCam using 15 imaging filters and 2 grismbandpasses. Further, parts of the JOF have deep 43 hr MIRI observations inF770W. Taken together, the JOF will soon be one of the most compelling deepfields available with JWST and a powerful window into the early Universe. Thispaper presents the second data release from JADES, featuring the imaging andcatalogs from the year 1 JOF observations.
