An energetic dirty fireball detected in soft X-rays
C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76
The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
A 50 s quasi-periodic oscillation in the early X-ray afterglow of GRB 220711B
H. Gao, W. -H. Lei, S. Xiao +19
It is generally believed that long duration gamma-ray bursts (GRBs) originate from the core collapse of rapidly spinning massive stars and at least some of them are powered by hype…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
An extremely soft and weak fast X-ray transient associated with a luminous supernova
W. -X. Li, Z. -P. Zhu, X. -Z. Zou +101
Long gamma-ray bursts (LGRBs), including their subclasses of low-luminosity GRBs (LL-GRBs) and X-ray flashes (XRFs) characterized by low spectral peak energies, are known to be ass…
