A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black ...

Astronomers have discovered the most distant mini-halo ever seen—10 billion light-years away—revealing that galaxy clusters ...

LOFAR is a massive radio telescope that comprises 100,000 antennas spread across eight European countries. The researchers ...

LOFAR detects a faint radio 'mini-halo' from 3.8 billion years ago, revealing how galaxy clusters evolved in the early ...

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that ...

An early universe radio jet spanning an astonishing 200,000 light years has been discovered by the International Gemini ...

A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

Scientists have discovered the farthest-ever 'mini-halo,' a sea of charged particles around a distant galaxy cluster that ...

Our LOFAR survey only covered 15 percent of the sky. And most of these giant jets are likely difficult to spot, so we believe there are many more of these behemoths out there.” ...

The jet is known as Quasar J1601+3102, and it was first spotted by astronomers using the Low Frequency Array (LOFAR). Researchers estimate that the jet spans nearly 200,000 light-years, more than ...

The discovery marks the most distant mini halo ever found, doubling the distance of any previously known example. It offers ...

Before the LOFAR observations, large jet systems were thought to be rare and expected to be smaller in size. Before Porphyrion was spotted, the largest confirmed black hole jet system was Alcyoneus.
