A astronomers from the University of Montreal (Canada) discovered it. It is a huge cloud of energy particles (a 'mini halo'). Surrounds one of the most distant galaxies clusters ever observed. It is a great step forward to understand the formation of the primitive universe.
In the early universe, the clusters of galaxies were already formed by energy processes. The detected minihalo is formed by loaded and highly energy particles in the void among the galaxies of a cluster. Together they emanate radio waves that can be detected from Earth.
Radio Calescope
The researchers analyzed data from the Lofar radio. It is a vast network of more than 100,000 small antennas that covers eight European countries. They detected a weak and extensive radio signal. It did not come from individual galaxies, but from a vast region of space full of high -energy particles and magnetic fields.
It has an extension of more than one million light years. The diffuse glow is an indication of a minihalo. It is a structure that, until now, astronomers have only been able to observe in the nearby universe. «It is as if we had discovered a vast cosmic ocean. Clusters of whole galaxies are constantly immersed in high -energy particles ». It is believed that there are supermassive black holes in the heart of the galaxies inside a cluster. They expel high energy particles to space.
The finding is a rare vision of what the clusters of galaxies were just after forming. The clusters of galaxies have been impregnated with these high -energy particles for billions of years. Now astronomers can study where these high -energy particles come from. They suggest that black holes cast out the environment of galaxies clusters long earlier than expected. They energize them for billions of years.
New perspectives
With the development of new telescopes, such as Square Kilometer Array (SKA), scientists can detect even weaker signals. They seek to explore more thoroughly the role of magnetic fields. And cosmic rays and energy processes in the configuration of the universe.
"We are hardly scratching the surface of the energy that the primitive universe really had." This discovery opens a new perspective on how galaxies clusters grow and evolve. The formation of the primitive universe would always be driven by black holes and high -energy particle physics.
