Census for the rest-frame optical and UV morphologies of galaxies at z = 4-10: First phase of inside-out galaxy formation
Ono, Yoshiaki; Ouchi, Masami; Harikane, Yuichi +7 more
We present the rest-frame optical and UV surface brightness (SB) profiles for 149 galaxies with Mopt < -19.4 mag at z = 4-10 (29 of which are spectroscopically confirmed with JWST NIRSpec), securing high signal-to-noise ratios of 10-135 with deep JWST NIRCam 1-$5\, \mu$m images obtained by the CEERS survey. We derive morphologies of …
Giant molecular clouds and their type classification in M 74: Toward understanding star formation and cloud evolution
Kobayashi, Masato I. N.; Tokuda, Kazuki; Tachihara, Kengo +10 more
We investigated the giant molecular clouds (GMCs) in M 74 (NGC 628), using data obtained from the PHANGS (Physics at High Angular resolution in Nearby GalaxieS) project. We applied GMC types according to the activity of star formation: Type I without star formation, Type II with H
Crimson Behemoth: A massive clumpy structure hosting a dusty AGN at z=4.91
Casey, Caitlin M.; Kartaltepe, Jeyhan S.; Koekemoer, Anton M. +40 more
The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase towards a more luminous and unobscured state. However, our understanding of dusty AGNs and their host galaxies at early cosmic times is inadequate due to observational l…
Low abundances of TiO and VO on the dayside of KELT-9 b: Insights from ground-based photometric observations
Ikuta, Kai; Fukui, Akihiko; Narita, Norio +21 more
We present ground-based photometric observations of secondary eclipses of the hottest known planet KELT-9 b using MuSCAT2 and Sinistro. We detect secondary eclipse signals in i and
