Gamma-Ray Bursts

    Gamma-Ray Bursts (GRBs) are astrophysical transients with extreme brightness in gamma-rays in a very short time. They are one popular classe of astrophysical objects to produce ultra-high energy cosmic rays (UHECRs).

    We are interested in the source physics of GRBs, including the production and escape of cosmic rays, neutrinos, and gamma-rays. We also study the propagation of UHECR, leading to the secondary production of neutrinos -- so-called cosmogenic neutrinos -- and other radiation products. We in addition use multi-messenger observations to constrain the properties of the sources and the cosmological distribution of the GRBs.
