Astronomers studying\u00a0a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe.<\/p>\n
While studying the distant galaxy cluster<\/a> known as SpARCS1049, astronomers detected faint mysterious radio waves, according to a study published in TheAstrophysical Journal Letters and available on the pre-print server Xrxiv.<\/p>\n The discovered radio waves, which took 10 billion years to reach Earth, originated from a\u00a0vast region of space\u00a0filled with high-energy particles and magnetic fields.<\/p>\n These vast clouds of high-energy particles are known as a mini-halo. A mini-halo has never been detected this deep into space<\/a> before, according to the study.<\/p>\n Mini-halos are described in the study as faint groups of charged particles. These groups are known to emit both radio and X-ray waves. Mini-halos are typically found in clusters between galaxies.<\/p>\n The discovered radio waves originated from a\u00a0vast region of space\u00a0filled with high-energy particles and magnetic fields. Astrophysics of Galaxies<\/p>\n Roland Timmerman of the Institute for Computational Cosmology of Durham University and co-author of the study said in a statement in Phys.org how these particles are important for the creation of our universe.<\/p>\n \u201cIt\u2019s astonishing to find such a strong radio signal at this distance,\u201d Timmerman said. \u201cIt means these energetic particles and the processes creating them have been shaping galaxy clusters<\/a> for nearly the entire history of the universe.\u201d<\/p>\n The astronomers analyzed data from the Low Frequency Array (LOFAR)\u00a0radio telescope. The LOFAR is made up of 100,000 small antennas across eight European countries, according to the study.<\/p>\n A mini-halo has never been detected this deep into space before, according to the study. Astrophysics of Galaxies<\/p>\n The team of astronomers believes there are two causes for the makeup of these mini-halos.<\/p>\n According to the study, the first explanation is\u00a0supermassive black holes\u00a0found at the heart of galaxies. These black holes can release high-energy particles into space<\/a>.<\/p>\n The astronomers are perplexed as to how these particles would escape such a powerful black hole to create these clusters.<\/p>\n The LOFAR is made up of 100,000 small antennas across eight European countries, according to the study. Chandra X-ray Center<\/p>\n The second explanation, according to the study, is cosmic particle collisions.\u00a0<\/p>\n These cosmic particle collisions occur when charged particles filled with hot plasma collide at near-light speeds. These collisions smash apart, allowing the high-energy particles to be observed from Earth.<\/p>\n According to the study, astronomers now believe that this discovery suggests that either black holes or particle collisions have been energizing galaxies earlier than previously believed.<\/p>\n The astronomers are perplexed as to how these particles would escape such a powerful black hole to create these clusters. Astrophysics of Galaxies<\/p>\n New telescopes\u00a0being developed like the Square Kilometer Array will eventually let astronomers detect even more faint signals.<\/p>\n Julie Hlavacek-Larrondo from the University of Montreal and co-lead author of the study said in a statement she believes this is just the beginning to the wonders of space<\/a>.<\/p>\n
