VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?

Yoshihisa Asada, Seiji Fujimoto, Joseph F. V. Allingham +50

The paper reports the discovery and detailed study of a type IIP core‑collapse supernova (SN Eos) at redshift 5.13, whose ultra‑faint, strongly lensed host galaxy is extremely meta…

VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325

Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75

We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…

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…

HST Confirms Sub-5 kpc Dual Quasar Pairs at Cosmic Noon

Qian Wang, Xuheng Ding, John Silverman +12

During cosmic noon (), when both star formation and black hole growth peaked, galaxy mergers are predicted to trigger dual active galactic nuclei (AGN) that eventually co…

Comprehensive JWST+ALMA Study on the Extended Ly Emitters, Himiko and CR7 at : Blue Major Merger Systems in Stark Contrast to Submillimeter Galaxies

Tomokazu Kiyota, Masami Ouchi, Yi Xu +14

We present various properties of two bright extended Ly objects, Himiko and CR7, at thoroughly investigated with JWST/NIRCam photometry, NIRSpec-IFU spectroscopy, and A…

Serendipitous Discovery of an Optically-Dark Ultra-Luminous Infrared Galaxy at = 3.4

N. H. Hayatsu, Zhi-Yu Zhang, R. J. Ivison +10

Dusty, submillimeter-selected galaxies without optical counterparts contribute a non-negligible fraction of the star formation in the early universe. However, such a population is…
