Double-Peaked Optical Afterglow in GRB 110213A Inferring a Magnetized Thick Shell Ejecta
Yo Kusafuka, Kaori Obayashi, Katsuaki Asano +1
Gamma-ray bursts early afterglows are important tracers for determining the radial structure and magnetization of the ejecta. In this paper, we focus on GRB 110213A that shows doub…

Two-component jet model for the afterglow emission of GRB 201216C and GRB 221009A and implications for jet structure of very-high-energy gamma-ray bursts
Yuri Sato, Kohta Murase, Yutaka Ohira +2
In recent years, afterglow emission in the very-high-energy (VHE) band above 100 GeV has been clearly detected for at least five gamma-ray bursts (GRBs 180720B, 190114C, 190829A, 2…
