{ "abstract": "We present a sample of 2081 sources selected at a photometric redshift z phot > 8 across the JADES DR5 data release in GOODS-S and GOODS-N over a total area of 469 arcmin 2 . These sources range from M UV = −22 to M UV = −16, with 19 objects at z phot > 14. We estimate the UV slopes for the full sample from fits to the photometry and find evidence for a steepening of the relationship between the UV continuum slope and M UV to higher redshifts, a result that differs from prior analyses of brighter samples in the literature. We provide evidence that over one-quarter of our sources have evidence for being morphologically extended, with many galaxies showing multiple bright knots or clumps even out to z ∼ 13–14, an indication of how galaxies at cosmic dawn are growing and evolving. We discuss JADES-GN+189.15982+62.28899, a GOODS-N F200W dropout galaxy at z phot ∼ 15–18, which has been observed spectroscopically with JWST/NIRSpec in prism mode, resulting in a very low signal-to-noise spectrum that is consistent with the photometry and rules out a number of low-redshift solutions for the source. Finally, we use a subsample of 123 objects in our sample with spectroscopic redshifts to explore the usage of alternate fitting templates and a prescription for Ly α damping wing absorption, finding that both produce significant improvements to the estimated photometric redshifts.", "abstract_shown": true, "affiliations": [ "University of Arizona", "Center for Astrophysics ∣ Harvard & Smithsonian", "University of Cambridge", "University of California", "Cosmic Dawn Center (DAWN)", "University of Copenhagen", "The Pennsylvania State University", "Centro de Astrobiología (CAB)", "University of Oxford", "Scuola Normale Superiore", "Sorbonne Université", "University of Hertfordshire", "The Johns Hopkins University", "University College London", "Space Telescope Science Institute", "Max-Planck-Institut für extraterrestrische Physik (MPE)", "NSF-DOE Vera C.
