JWST, ALMA, and Keck Spectroscopic Constraints on the UV Luminosity Functions at z ∼ 7–14: Clumpiness and Compactness of the Brightest Galaxies in the Early Universe by Yuichi Harikane, Akio K. Inoue, Richard S. Ellis, Masami Ouchi, Yurina Nakazato, Naoki Yoshida, Yoshiaki Ono, Fengwu Sun, Riku A. Sato, Giovanni Ferrami, Seiji Fujimoto, Nobunari Kashikawa, Derek J. McLeod, Pablo G.

Koekemoer, Nicolas Laporte, Chien-Hsiu Lee, Dan Magee, Hiroshi Matsuo, Yoshiki Matsuoka, Ken Mawatari, Kimihiko Nakajima, Minami Nakane, Yoichi Tamura, Hiroya Umeda, Hiroto Yanagisawa

“…Our sample is composed of 60 galaxies at z _spec ∼ 7–14, including recently confirmed galaxies at z _spec = 12.34–14.18 with JWST, as well as new confirmations at z _spec = 6.583–7.643 with −24 < M _UV < −21 mag using ALMA and Keck. Our JWST/NIRSpec observations have also revealed that very bright galaxy candidates at z ∼ 10–13 identified from ground-based telescope images before JWST are passive galaxies at z ∼ 3–4, emphasizing the necessity of strict screening and spectroscopy in the selection of the brightest galaxies at z > 10. …”
