Gamma-ray
bursts, the most violent cosmological explosions in the Universe appear
ramdomly over the sky as brief and highly variable X-/Gamma-ray
flashes. Their energy throughput is so large that they could be
detected up to redshifts of 10. They are thought to be associated with
the launch of ultra-relativistic jets from an accreting newly-born
black hole or magnetar (i.e. a neutron star with an extreme magnetic
field up to 1015 Gauss) following the merger of two compact objects or the core collapse of some massive stars. |
