A sub-100 pc view at z~5 of a Multiply-Imaged Massive Quiescent Galaxy

Richard Pan, Danilo Marchesini, Joseph F. V. Allingham +34

Recent James Webb Space Telescope spectroscopic surveys reveal an abundance of rapidly assembled early galaxies in the first billion years. Cosmological simulations struggle to rep…

VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at z=5.13 Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?

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

We present the first characterization of the host galaxy of a recently discovered type IIP SN at z=5.13 (SN Eos). SN Eos and its host galaxy are gravitationally lensed and multip…

Caught in Swallowtails: Discovery of Two Swallowtail Image Formations in MS 0451.6-0305

Ashish K. Meena, Wenlei Chen, Lukas J. Furtak +6

We report the discovery of two swallowtail image formations at z=2.91 and z=6.70 behind the galaxy cluster MS 0451.6-0305 in JWST-NIRCam imaging. We find that in both of the ab…
