For many years, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars—probably the most mysterious objects within the universe.
Astrophysicists consider that this high-energy radiation—which makes neutron stars and black holes shine bright—is generated by electrons that transfer at practically the speed of light; however, the course of that accelerates these particles has remained a mystery.
Now, researchers at Columbia University have offered a brand new explanation for the physics underlying the acceleration of those energetic particles.
In an examine revealed within the December issue of The Astrophysical Journal, astrophysicists Luca Comisso and Lorenzo Sironi employed huge super-computer simulations to calculate the mechanisms that speed up these particles. They even concluded that their energization is a result of the interaction between chaotic motion and reconnection of super-strong magnetic fields.
When learning turbulent gas, scientists can’t predict chaotic movement exactly. Coping with the mathematics of turbulence is tough, and it constitutes one of many seven “Millennium Prize” mathematical issues. To sort out this problem from an astrophysical viewpoint, Comisso and Sironi designed extensive tremendous-computer simulations —among the many worlds largest ever done on this analysis area—to solve the equations that describe the turbulence in a fuel of charged particles.
The ultimate purpose, the researchers, stated, is to get to know what is really happening within the extreme environment surrounding neutron stars and black holes, which might shed further light on fundamental physics and enhance the understanding of how the Universe works.
