Off-axis jet scenario for early afterglow emission of low-luminosity gamma-ray burst GRB 190829A
Yuri Sato, Kaori Obayashi, Ryo Yamazaki +2
Recently, ground-based Imaging Atmospheric Cherenkov Telescopes have reported the detection of very-high-energy (VHE) gamma-rays from some gamma-ray bursts (GRBs). One of them, GRB…

Less noticeable shallow decay phase in early X-ray afterglows of GeV/TeV-detected gamma-ray bursts
Ryo Yamazaki, Yuri Sato, Takanori Sakamoto +1
The nature of the shallow decay phase in the X-ray afterglow of the gamma-ray burst (GRB) is not yet clarified. We analyze the data of early X-ray afterglows of 26 GRBs triggered b…
