Predicting Multiwavelength Emission Associated with X-Ray Flares and Extended Emission of Gamma-Ray Bursts
Riki Matsui, Shigeo S. Kimura, Kohta Murase +1
Gamma-ray bursts (GRBs) are one of the most extreme transients in the universe, but their explosion and emission mechanism remains unclear. To investigate the nature of GRB jets, h…

High-energy neutrinos from late-time jets of gamma-ray bursts seeded with cocoon photons
Riki Matsui, Shigeo S Kimura, Hamid Hamidani
In gamma-ray bursts (GRBs), 100 - 1000 s after the prompt emission, afterglow observations have consistently shown X-ray excesses detected in the form of flares (XFs; in lon…
