Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf

Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103

A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…

XRF 241001A/SN 2024aiiq: A faint soft X-ray transient detected by SVOM with a broad-line type Ic supernova revealed by JWST

B. Schneider, M. Brunet, B. P. Gompertz +61

X-ray flashes (XRFs) are a type of gamma-ray burst (GRB) with prompt emission predominantly below 30 keV and have been poorly detected by previous missions. The advent of the SVOM…
