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…

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-…

Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a
Y. Liu, H. Sun, D. Xu +191
Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…
