According to a new study, astronomers have detected a huge cloud of energetic particles-a ‘mini-heelo’-around one of the last galaxy groups. This mini-hillo is so far away that its light takes about 10 billion years to reach the Earth, making it the farthest mini-halo that has been discovered so far and doubles the record of the previous distance. The discovery suggests that even in the very early universe, large-scale galaxy groups were already filled with high-energy particles. The International Research Team was co-Nedicated by Julie Hlavsek Laudo and Rolland Timmerman.
The unconscious radio brightly reveals mini-halo
As Study, Team used European Low Frequency Array (Lofar) radio telescope To study distant cluster sparcs1049. LOFAR – A network of over 100,000 antennas spread over eight European countries – an extremely unconscious, dilated radio signal around the cluster. This brightness extends to more than one million light-year, which reveals a spacious “mini-halo” of high-energy particles and magnetic fields.
Analysis showed that emissions are filled space Instead of coming from any galaxy, between the galaxies. The cluster lights took 10 billion years to reach us, doubled the record of distance for any known mini-halo. Recearch co-leader Julie Hlavacek-Larrondo described it as a huge cosmic ocean, in which the entire galaxy groups are constantly submerged into high-energy particles.
Origin of mini-halo
There are two main principles for the origin of Mini-Hello. One possibility is that the powerful jet from the supermasive black hole in the cluster galaxies has injected energetic particles into space. However, it is not clear how such particles can travel away from the galaxy centers without losing their energy.
Another idea is that the cluster of the cluster makes collision particles. In this scenario, the particles charged in the intrachluster plasma were crashed at near-light speed, producing high-energy particles seen. These comments mean that large -scale groups were already filled with energetic particles long before. Future devices such as square kilometers array (SKA) will also get mini-hillos, which will help scientists to study the roles of magnetic fields and cosmic rays in cluster development.
