Abstract:
We report the discovery of eight transient sources likely at redshifts z = 0.665-1.764, each discovered in the GOODS-South (GOODS-S) field using the 9-band JWST/NIRCam imaging data obtained by the JWST Advanced Deep Extragalactic Survey (JADES). These transients appear as point sources in the NIRCam Short-Wavelength (SW) images but are not seen in any of the archived GOODS-S HST images over the same wavelength range.

The JWST Advanced Deep Extragalactic Survey (JADES) obtained Cycle-1 NIRCam images of the GOODS-S field using 4 short-wavelength (SW) filters (F090W, F115W, F150W, and F200W) and 5 long-wavelength (LW) filters (F277W, F335M, F356W, F410M, and F444W). The data were taken in two time periods, UT Sep 29 - Oct 5, 2022 and Oct 7 - 11, 2022, targeting two neighboring areas.  Five transients were detected with the first data set while three appeared in the second, with respect to the GOODS-S HST mosaic images (v2.0) distributed by the Hubble Legacy Fields (HLF) project (https://archive.stsci.edu/prepds/hlf).  Below we list the position, photometry and redshift information for each of these sources. The information on the host galaxies were obtained either from NED, SIMBAD, or the 3D-HST+CANDELS Catalog, and all the reported magnitudes are in AB.
