Shocking Results of Galaxy-Cluster Collisions

A hulk collision of several universe clusters, any containing hundreds of galaxies, has constructed this fantastic scenery of shocks and energy. The collisions generated startle waves that set off a astronomical fireworks arrangement of splendid radio emission, seen as red and orange. In a core of a image, a purple indicates X-rays caused by impassioned heating.

The segment is collectively famous as Abell 2744, some 4 billion light-years from Earth. The radio apportionment of a picture comes from new observations done with a National Science Foundation’s Karl G. Jansky Very Large Array (VLA), and is total with progressing information from NASA’s Chandra X-ray observatory. Both are overlaid on an picture during visible-light wavelengths done with information from a Subaru telescope and a Very Large Telescope (VLT). The new VLA observations suggested formerly undetected regions where shocks accelerated subatomic particles, causing radio emission.

Astronomers are study a total picture in an try to interpret a method of galaxy-cluster collisions. Currently, they said, justification indicates a North-South (top-bottom in a image) collision of subclusters and an East-West (left-right in a image) collision. There is a probable third collision, and a astronomers continue to investigate their information to expose some-more sum about a region’s formidable story of collisions and their aftermath.

The scientists reported their commentary in a paper in a Astrophysical Journal by Connor Pearce, of a Harvard-Smithsonian Center for Astrophysics and a University of Southampton in a UK, and an general group of colleagues.

The National Radio Astronomy Observatory is a trickery of a National Science Foundation, operated underneath mild agreement by Associated Universities, Inc.
