The center of the Milky Way hides a huge particle accelerator

A team of researchers from the Chinese Academy of Sciences found evidence of the existence of a powerful accelerator

particles in the center of the galaxy. In an article published in the journal Nature Communications, scientists tell how they analyzed the data obtained using the Fermi Large Area Telescope.

It is believed that in the center of the Milky Way isa large black hole and other objects such as supernova remnants. But little is known about the interior of the galactic center, mainly due to its density. However, most physicists agree that the very center of the Milky Way emits a huge number of rays, many of which reach Earth. In the new work, the researchers sought to learn more about them.

They analyzed the data collected by variousteams of scientists who work on the Fermi Large Area Telescope. They primarily focused on gamma rays from the central molecular cloud. It is composed of interstellar dust and hydrogen gas and is located between the Earth and the center of the galaxy. Physicists have found that the density of cosmic rays in the central molecular cloud is lower than in other regions. This allowed us to assume that there is some kind of barrier that prevents the penetration of rays into the central molecular cloud.

But they also found evidence thatcosmic rays slow down as they pass through the cloud and then accelerate again after exiting. This suggests that some object near the center of the Milky Way is serving as a particle accelerator. What exactly this is is not yet known, but scientists suggest that it could be a black hole Sagittarius A * or even a remnant of some kind of supernova.
