Title:
General Relativistic Magneto-Hydrodynamic Simulations of Gamma-Ray
Bursts
Abstract:
Gamma-Ray Bursts (GRBs) are the most powerful explosions in the
Universe. Recently, it is found that some GRBs are born with peculiar
supernova explosions. The explosion energy of the peculiar supernovae
is about 10 times greater than that of normal supernovae. That is why
it is believed that the central engine of GRBs is different from the
one of normal supernovae. However, it is not known well how the engine
of GRBs is working. In this talk, I would like to review the history of
the study on the central engine of GRBs and I would like to present my
recent numerical simulations (General Relativistic Magneto-Hydrodynamic
Simulations) of the engine. Also, I would like to show briefly some our
recent works that are related with GRB phenomena.
