Observing a distant cluster of galaxies has left scientists bewildered, as they believe they may have discovered a new form of physics.
Scientists Tessa Wernström of the University of Western Australia and Christopher Reisley of the University of Bologna, Italy, have discovered three large objects that emit low-frequency radio waves in a cluster of galaxies about 800 million light-years away. And they seem to defy the laws of physics, reports Futurism.
Clusters of galaxies are huge cosmic structures that can consist of hundreds or even thousands of galaxies. But the galaxies themselves occupy only a small part of such structures, the rest of the mass of the cluster is represented by the mysterious dark matter – a very hot gas, the temperature of which can be 10 million degrees Celsius.
Using radio telescopes and X-ray telescopes, scientists studied the Abell 3266 galaxy cluster, which is located at a distance of about 800 million light-years from us. In this cluster, they found three very rare large objects that emit radio waves – a fossil radio emission, a radio relic and a radio halo.
- A radio relic is an arc-shaped radio source located on the outskirts of a cluster of galaxies.
- A radio halo is a radio source that is closer to the center of a cluster of galaxies. Like a radio relic, these objects are formed as a result of collisions between clusters of galaxies.
- Fossil radio emission occurs after the death of a supermassive black hole at the center of a radio galaxy.
Scientists have been suggesting for several years that all three very rare objects that emit radio waves can be found in the Abell 3266 galaxy cluster. But these three radio sources were too weak to be detected, but the scientists succeeded. The researchers also found the remains of a supermassive black hole in a cluster of galaxies.
The radio relic that scientists discovered in the Abell 3266 galaxy cluster was of particular interest to them, as it does not look like any other radio object, which scientists have ever seen before, due to its very unusual shape.
“The data we obtained does not quite match our understanding of how similar objects are created that we found in this cluster of galaxies. Our best physical the models just can't match that data, which means that different physics could have been involved in the creation of these objects. We got a lot of new information, but also we have even more unanswered questions. But we will work on it, “says Wernstrom.
As Focus already wrote, Scientists first discovered dark matter, which is 12 billion years old. New research could change our understanding of the cosmos.
