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…
GRB 180728A and SN 2018fip: the nearest high-energy cosmological gamma-ray burst with an associated supernova
A. Rossi, L. Izzo, K. Maeda +29
The long GRB 180728A, at a redshift of , stands out due to its high isotropic energy of erg, in contrast with most events at redshi…
The puzzling long GRB 191019A: Evidence for Kilonova Light
G. Stratta, A. M. Nicuesa Guelbenzu, S. Klose +11
GRB 191019A was a long Gamma-ray burst (GRB) lasting about 65 s and, as such, originally thought to be linked to a core-collapse supernova. However, even though follow-up observati…
The GROND gamma-ray burst sample. I. Overview and statistics
J. Greiner, T. Krühler, J. Bolmer +17
A dedicated gamma-ray burst (GRB) afterglow observing program was performed between 2007 and 2016 with GROND, a seven-channel optical and near-infrared imager at the 2.2m telescope…
