A computer simulation of a black hole has revealed that magnetic fields generate the massive flares that sometimes erupt from stellar objects, scientists said in a study first released last month.
According to research co-led by Dr. Bart Ripperda of the Flatiron Institute in New York City, the bright-light bursts of previously unknown origin that came just outside a black hole’s event horizon were caused by powerful surrounding magnetic fields. The phenomenon has been known for some time, but computer simulations allowed the researchers to get more insight into its nature.
The results were first made available on January 14 and published in the Astrophysical Journal Letter of the American Astronomical Society.
The research team used three separate supercomputer clusters to produce a highly detailed model of the processes that happen outside the event horizon. This allowed them to achieve images at a resolution 1,000 times greater than was previously possible, according to the report of the Flatiron Institute’s Center for Computational Astrophysics (CCA).
