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…
Spatial decomposition of Little Red Dots with JWST/NIRSpec IFU into broad-line red cores and narrow-line blue host galaxies
Yuzo Ishikawa, Anna-Christina Eilers, Rohan P. Naidu +11
Little Red Dots (LRDs) are a population of compact red sources discovered by the James Webb Space Telescope (JWST). Imaging and spectroscopy have shown that LRDs exhibit a complex…
Lyman-alpha haloes in the aftermath of reionisation
Daniil Smirnov, Lutz Wisotzki, Tanya Urrutia +8
We present a comparative study of Ly haloes (LAHs) around low-luminosity (L erg s) Ly-emitting galaxies (LAEs) at very high redshif…
Euclid: Discovery of 31 new quasars at
D. Yang, J. F. Hennawi, F. Guarneri +211
We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…
Little Red Dots at z~2 in EIGER reveal a gentle decline with respect to their peak number density at z~5
Shrriya Kapoor, Jorryt Matthee, Alberto Torralba +10
We report the discovery of a sample of little red dots (LRDs) at identified from deep JWST/NIRCam imaging and wide-field slitless spectroscopy over arcmin f…
Possible chemical signatures of first-star enrichment in a very metal-poor galaxy overdensity near the end of reionization
Zihao Li, Koki Kakiichi, Lise Christensen +24
The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…
