Redshift vs. M _UV. The magnification correction is applied for the lensed sources. The red circles represent our spec-z-confirmed sources in UNCOVER at z ≥ 8.5, efficiently increasing the sample at the faint (M _UV ≳ − 19) and high-redshift (z ≳ 9.5) regime. The gold pentagons and the black squares show recent JWST spectroscopic results from other field surveys such as JADES (e.g., A. J. Bunker et al. 2023), FRESCO (e.g., P. A. Oesch et al. 2023), and CEERS (e.g., S. L. Finkelstein et al. 2023), where the values are taken from K. N. Hainline et al. (2024). The blue triangles denote recent JWST/NIRSpec observation results for high-redshift lensed galaxies (C. C. Williams et al. 2023; T. Y.-Y. Hsiao et al. 2024). The gray crosses indicate the photometric candidates with NIRCam publicly available in JADES v1.0 catalog (K. N. Hainline et al. 2024).
