Sentences with phrase «colliding galaxy clusters»

Individually, both supermassive black holes and colliding galaxy clusters are among the most powerful phenomena in the universe, but they had never been observed clearly linked together.

Then two massive colliding galaxy clusters in the constellation Carina caught the attention of Marusa Bradac of the Kavli Institute at Stanford University and her colleagues, who saw this cosmic smashup as a chance to watch dark matter in action.

The research, also posted online at arXiv.org, negates an earlier finding that stars were separated from their dark matter in Abell 3827, a cluster including four colliding galaxies about 1.3 billion light - years from Earth (SN: 5/16/15, p. 10).

A study of 72 large cluster collisions shows how dark matter in galaxy clusters behaves when they collide.

Here are images of six different galaxy clusters taken with NASA's Hubble Space Telescope (blue) and Chandra X-ray Observatory (pink) in a study of how dark matter in clusters of galaxies behaves when the clusters collide.

In an effort to learn more about dark matter, astronomers observed how galaxy clusters collide with each other — an event that could hold clues about the mysterious invisible matter that makes up most of the mass of the universe.
