JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
The influence of feedback on the baryonic content of haloes in the COLIBRE simulations
Jonathan J. Davies, Joop Schaye, Filip Huško +7
The paper uses the COLIBRE cosmological simulations to study how supernova and AGN feedback affect the gas mass fraction of dark matter haloes across different masses, showing a no…
Gamma-ray burst progenitors revisited
Andrew J. Levan, Jillian C. Rastinejad, Helena-Margaret S. Grabham +11
The paper examines nearby long-duration gamma-ray bursts that lack supernova signatures, finding that many may originate from compact object mergers rather than massive stars, and…
Coupled Shock Cooling and Radioactive Heating in the Type IIb Supernova SN 2024aecx: An Extended Envelope and Rapid Optical Decline
Na Wei, Yu-Hao Zhang, Liang-Duan Liu +4
The paper models the double-peaked light curve of the Type IIb supernova SN 2024aecx by combining early shock‑cooling emission with later radioactive heating in a time‑dependent ra…
