Discovery of ‘mini halo’ points to how the early universe was formed

TLDR:

* Astronomers co-led by Julie Hlavacek-Larrondo of Université de Montréal and Roland Timmerman of the Institute for Computational Cosmology of Durham University, in the U.K have discovered the most distant “mini-halo” of energetic particles, located in a galaxy cluster 10 billion light-years away, indicating that even in the early universe, large galaxy clusters were immersed in high-energy particles.
* This mini-halo, a vast cloud of charged particles emitting radio waves, suggests that energetic processes like supermassive black hole ejections or cosmic particle collisions have been shaping galaxy clusters for nearly the entire history of the universe.
* The discovery provides new insights into the early universe and how galaxy clusters grow and evolve, highlighting the long-standing influence of black holes and high-energy particle physics.
