Scientists have discovered radio waves emerging from space between a pair of galaxy clusters – evidence of intergalactic magnetic fields and fast moving particles in the space between these huge galactic arrays.
The universe consists of a vast network of galaxy clusters sitting at the interface of filaments. Galactic filaments are massive, thread-like material formations that make up the large-scale structure of the universe. So far, scientists have known about 10 million light years of filament connecting the galaxy clusters Abell 0399 and 0401 to magnetic fields within the clusters. However, they wondered if this filament itself contained magnetic fields and relativistic particles (ie, particles accelerated to near-velocity) light).
This, according to the authors of the study, is the first evidence of a magnetized filament and will hopefully help them better understand the formation of the large-scale structure of the universe.
"From a theoretical point of view this is the case A real challenge to explain this radio emission," said Federica Govoni, the first author of the study of the Italian Istituto Nazionale di Astrofisica (Cagliari Observatory), to Gizmodo of thousands of radio antennas Dozens of stations, mainly in the Netherlands, to search for low-frequency radio wave emissions between galaxies. They interpret the signal as the presence of synchrotron radiation or particles spiraling due to the influence of a magnetic field at near the speed of light.
