Abstract
Abstract We conduct a comprehensive study on dropout galaxy candidates at z ∼ 9–16 using the first 90 arcmin 2 James Webb Space Telescope (JWST) Near Infrared Camera images taken by the early release observations (ERO) and early release science programs. With the JWST simulation images, we find that a number of foreground interlopers are selected with a weak photo- z determination (Δ χ 2 > 4). We thus carefully apply a secure photo -z selection criterion (Δ χ 2 > 9) and conventional color criteria with confirmations of the ERO Near Infrared Spectrograph spectroscopic redshifts, and obtain a total of 23 dropout galaxies at z ∼ 9–16, including two candidates at z phot = 16.25 − 0.46 + 0.24…
