In the pre-merger hotline, astronomers first discovered the "wave bridge" between the two clusters.

We know that there are actually a series of "bridges" connected between the various galaxies and clusters of the universe. They are composed of dark matter, dust and gas, forming an orderly universe. Recently, astronomers have for the first time discovered a special "radio wave bridge" between two clusters of galaxies, stretching over 10 million light years and carrying magnetic fields, allowing scientists to learn more about the large-scale structure of the universe.

In cosmic physics, fibrous structures are the largest known structures. These "fibers" are assumed to be composed of invisible dark matter and visible dust and gas. You can imagine that the structure of the universe is like a net, and those lines are thin. And the fibrous structure that is difficult to observe, the point where the line intersects the line is a galaxies or clusters of galaxies. As for the one-frame-shaped holes between the lines, we call them "Voids". These areas (interstellar) Space) basically no galaxies.So far, we have found in the "points" those galaxies and galaxies (except visible light, infrared, X-ray, gamma rays, radio, etc.) that are filled with hot gases and stars, in contrast to fibers. Although the length of the structure can extend hundreds of millions of light years, it is relatively elusive, and scientists have never observed a magnetic field in these filamentous structures.However, the team led by the Italian Institute of Astrophysics (INAF) astronomer Federica Govoni, after observing the Abell 0399 and Abell 0401 clusters using the Low-Frequency Array (LOFAR) radio telescope, was surprised to find two clusters. Connect the "Radio Wave Bridge".Before the study, scientists already knew that the two clusters were surrounded by radio magnetic fields, and the Planck satellite recently confirmed that the two clusters were connected to each other through the slender fibrous structure, which triggered researchers' curiosity and speculation whether the magnetic field of the galaxy cluster had Filaments that may extend beyond the point? It turns out that the researchers are bet on it. Abell 0399, Abell 0401 These two clusters of galaxies are currently about 9.8 million light-years apart, about 1 billion light-years away, and are destined to collide and merge into a larger superclusters in the future, when researchers observe the cluster of galaxies. During the interstellar space, an obvious "radio wave bridge" was found connecting two clusters.After further computer simulations, the researchers proposed a possible explanation for this phenomenon. This radio wave emits a strong shock wave from a weak magnetic field (one million times weaker than the Earth's magnetic field), and then accelerates a large number of electrons into relativistic particles (close to Particles moving at the speed of light) ran between two clusters of galaxies along a fibrous structure.In other words, the Abell 0399, Abell 0401 clusters are busy disrupting each other, throwing shock waves and a large number of relativistic particles into the intergalactic space.The magnetic field of fibrous structures often exceeds the detection limits of today's telescopes, so researchers are not sure whether all fibrous structures have magnetic fields, and as future observations may help astronomers understand more about how large-scale structures of the universe are formed.
