Record 10-Billion-Year Radio Halo Sheds New Light on Universe’s Origins

Fast Summary

• Astronomers discovered a vast cloud of energetic particles, called a “mini-halo,” surrounding one of the most distant galaxy clusters ever observed.
• Located 10 billion light-years away, this is the most distant mini-halo discovered, doubling the previous record.
• Mini-halos are composed of highly energetic charged particles in space between galaxies within clusters that emit radio waves detectable from Earth.
• Findings suggest galaxy clusters have been immersed in high-energy processes for nearly the universe’s entire history.
• Research was conducted by an international team led by Julie Hlavacek-Larrondo (Université de Montréal) adn Roland Timmerman (Durham University).
• Using data from LOFAR radio telescope, scientists studied galaxy cluster SpARCS1049 and identified faint radio signals emanating from high-energy particles and magnetic fields spread across over a million light-years.
• Researchers proposed two main explanations for mini-halo formation: supermassive black holes ejecting streams of high-energy particles or cosmic particle collisions within hot plasma at near-light speeds.
• This finding sheds new light on early galaxy cluster formations and contributes to understanding how they evolve through high-energy processes triggered billions of years ago.
• Future advancements like Square Kilometer Array (SKA) telescopes will enable further exploration into magnetic fields, cosmic rays, and energetic phenomena shaping the cosmos.
