The JADES Origins Field: A New JWST Deep Field in the JADES Second NIRCam Data Release

We summarize the properties and initial data release of the JADES Origins Field (JOF), which will soon be the deepest imaging field yet observed with the James Webb Space Telescope (JWST). This field falls within the GOODS-S region about $8\ \mathrm{arcmin}$ south-west of the Hubble Ultra Deep Field (HUDF), where it was formed initially in Cycle $1$ as a parallel field of HUDF spectroscopic observations within the JWST Advanced Deep Extragalactic Survey (JADES). This imaging will be greatly extended in Cycle $2$ program $3215$ , which will observe the JOF for $5$ days in six medium-band filters, seeking robust candidates for $z > 15$ galaxies. This program will also include ultra-deep parallel NIRSpec spectroscopy (up to $104\ \mathrm{hours}$ on-source, summing over the dispersion modes) on the HUDF. Cycle $3$ observations from program $4540$ will add $20\ \mathrm{hours}$ of NIRCam slitless spectroscopy to the JOF. With these three campaigns, the JOF will be observed for $380\ \mathrm{open-shutter\ hours}$ with NIRCam using $15$ imaging filters and $2$ grism bandpasses. Further, parts of the JOF have deep $43\ \mathrm{hours}$ MIRI observations in F770W. Taken together, the JOF will soon be one of the most compelling deep fields available with JWST and a powerful window into the early Universe. This paper presents the second data release from JADES, featuring the imaging and catalogs from the year $1$ JOF observations.
