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…
JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +42
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. \textit{JWST} near- and mid-in…
Single vs. Binary Origin: The Diversity of Stripped-Envelope Supernova Remnants
Gaku Kawashima, Shiu-Hang Lee, Keiichi Maeda +1
Core-collapse supernova remnants (CCSNRs) are crucial for understanding the final stages of massive star evolution, as they reflect the imprints of their progenitors' pre-explosion…
Revisiting the Suzaku spectrum of the Galactic SNR W 49 B: non-detection of iron K-shell charge exchange emission and refined ejecta mass ratios of iron-group elements
Makoto Sawada, Toshiki Sato, Keiichi Maeda +1
The origin of the recombining plasma in several Galactic SNRs has been debated. A plausible mechanism would be a rapid cooling in the past, either by adiabatic or conductive proces…
