The new theory could help explain some of the most mysterious and powerful objects in the universe, such as quasars and active galactic nuclei. These objects are thought to be powered by supermassive black holes, but the exact mechanisms for how they produce light are still not fully understood.
The ANU team, led by Dr. Christian Wolf, published their findings in the journal Nature Astronomy. They suggest that the light is produced by the interaction of strong magnetic fields around black holes and neutron stars with surrounding gas. This interaction creates shocks and sparks, which produce high-energy radiation in the form of X-rays and gamma rays.
"Our theory is that the bright light from black holes and neutron stars is caused by the interaction of strong magnetic fields with the surrounding gas," Dr. Wolf said. "This interaction creates shocks and sparks, which produce high-energy radiation."
The team used computer simulations to model the interaction of magnetic fields and gas around black holes and neutron stars. They found that the simulations produced light that was similar to the light observed from quasars and active galactic nuclei.
"Our simulations show that the interaction of strong magnetic fields with surrounding gas can produce light that is similar to the light observed from quasars and active galactic nuclei," Dr. Wolf said. "This suggests that our theory could provide a new explanation for how these objects shine bright."
The team's findings could help astronomers better understand some of the most mysterious and powerful objects in the universe.
