A UV-Luminous Galaxy at z=11 with Surprisingly Weak Star Formation Activity

Yuichi Harikane, Pablo G. Perez-Gonzalez, Javier Alvarez-Marquez +8

One of the major discoveries by the James Webb Space Telescope (JWST) is the identification of a large population of luminous galaxies at , challenging theoretical models for…

JWST Spectroscopic Census of ALMA Faint Submillimeter Galaxies in the Hubble Ultra Deep Field

Tomokazu Kiyota, Masami Ouchi, Daisuke Iono +6

We present a JWST/NIRSpec rest-frame optical spectroscopic census of ALMA 1-mm continuum sources in the Hubble Ultra Deep Field (UDF) identified by the deep ALMA UDF and ASPECS pro…

A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13

David A. Coulter, Conor Larison, Justin D. R. Pierel +88

Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…

VENUS: Two Faint Little Red Dots Separated by Hidden in a Single Lensed Galaxy at

Hiroto Yanagisawa, Masami Ouchi, Miriam Golubchik +47

We report the identification of a pair of faint little red dots (LRDs), dubbed Red Eyes, in a strongly-lensed galaxy at behind the PLCKG004.5-10.5 cluster, identified from…

DREAMS.II. Galaxy Demographics from Direct Te-Based Metallicities at z~2-10: Tracing the Evolution of the Mass-Metallicity and Fundamental Relations

Moka Nishigaki, Kimihiko Nakajima, Masami Ouchi +6

We present the statistics of line ratios and direct Te-based metallicities from JWST medium-resolution spectra of 292 galaxies at z=2-10, combining DREAMS observations with those o…

Little red dot variability over a century reveals black hole envelope via a giant Einstein cross

Zijian Zhang, Mingyu Li, Masamune Oguri +79

"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
