Scientists have always been speculating about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars. Now researchers have designed a model that shows how electrons taking a cosmic rollercoaster-ride through magnetic turbulence can produce electromagnetic radiation. They claimed that energization is an outcome of the interaction between chaotic motion and reconnection of the powerful magnetic fields. Researchers said the imitations showed that reconnection is the key mechanism that picks the particles that will be subsequently accelerated by the turbulent magnetic fields up to the highest energies.
