Simulación cinética de un shock relativista para estudiar los mecanismos de aceleración en la emisión temprana de un GRB

Abstract

Gamma Ray Burts (GRBs) are highly energetic radiation processes. The most accepted model to describe them is the standard Fireball model. This model describes possible regions where GRBs are produced, originated from relativistic shocks, generated by layers that move with different Lorentz factors. It is well accepted that in these shocks the charged particles are accelerated by fluctuations of the electromagnetic field. Having a composition of electrons, protons with low densities, the particles do not interact mutually, but by the interaction field-particle. Therefore, these shock are considered as collisionless plasma. In this research work we implemented a PIC algorithm for the description of these shock, considering that initially they are not magnetized.
