The explanation for the halo glows in the black hole

Astronomers from the US Aeronautics Agency (NASA) discovered corona halo containing high-energy particles that are responsible for glowing black holes.

The answer to the halo on the black hole

Observations from NASA's NuSTAR space telescope may have identified the source of extremely powerful X-ray rays emitted from massive black holes. According to NASA, this phenomenon is caused by a part of the black hole called corona halo .

The flashy black hole discovered by NuSTAR called Markarian 335 (Mrk 335) , is located in the constellation Pegasus 324 million light-years from Earth. While the black hole itself did not emit light, the telescopes could detect light produced by the black hole gravity gas, Mrk 335. As the gas approaches the event horizon, it becomes extremely hot and glows before disappearing.

The telescope helps detect light emitted by corona halo, a structure that includes high-energy particles, emitting light in the form of X-ray spectra . The researchers proposed two hypotheses about the structure of the halo.

The first hypothesis, the "lamp post" model , confirms the halo is a light source like a light bulb located above and below the black hole along its axis of rotation. The second hypothesis, also known as the "sandwich" model , suggests that corona halo forms a diffuse cloud form around a black hole, or the two flat parts that cover a black hole.

In September 2014, NASA's Swift telescope unexpectedly detected the X-ray glowing event that took place in the black hole Mrk 335 and astronomers quickly corrected NuSTAR lenses to continue monitoring.

Following the X-ray light, the scientists discovered that its origin was an aura halo coming out of the black hole. Moving at 20% of the speed of light, the halo formed at the bottom of the glow zone before dissipating into the universe.

The findings provide evidence for the "light pole" model , but many of the important characteristics of the halo are its mysteries and glowing mechanisms.
