Two Galaxy Bundles Are Connected Through a Mysterious, Long Magnetic Field

A new radio wave has been detected by scientists in the space between a pair of two galaxy bundles. This is the evidence of the intergalactic magnetic field and the fast-moving particles found in the area between them. When we look at the Universe, we see it composed of a vast network of galaxy bundles situated at the intersection of these galactic filaments. Moving further with the discovery, the scientist has recognized as the first detection of magnetized filament.

Returning to the galactic filaments, these formations are massive. They are formed from matter that is creating the structure of the Universe. The scientists have been aware of a filament of ten million light-years long that is linking the two galaxies bundles, named Abell 0399 and 0401. But they were curious if the magnetic field from the bundle is found on the filament itself.

Besides this, Federica Govoni, the study’s author from the Cagliari Observatory of Italy’s Institute of Astrophysics, is saying that it’s tough to explain the radio emission from a theoretical point of view. For going on with the study, the researchers have used the Low-Frequency Array (LOFAR), which is a telescope network that contains a sensitive system of thousands of radio antennas from a lot of stations. Most of the stations are in the Netherlands, and their purpose is to detect low-frequency radio-wave emissions from a pair of two galaxies. The signals have come as synchrotron radiation, or particles spiraling at light speed because a magnetic field influences them.

Finally, after that signal was received, the researchers were able to estimate what kind of strength had the magnetic field and even some hints of the substructure. Govoni says that after all the observations, measurements, and the discovery of the signature, she is more confident that what they are seeing is real. Further studies will be made to see if they could link other galaxies bundles and to find out if the phenomenon is universal.
