ESA XMM-Newton X-ray Observatory Observes Hot Gas Slosings in a Galaxy!

 ESA has announced that it has used the XMM-Newton X-ray Observatory to observe hot gas slosings inside a galaxy cluster for the first time. This behavior may be induced by turbulent merger events. The ESA states that galaxy clusters are the largest system in the universe combined with gravity. The bunches contain hundreds of thousands of galaxies and large quantities of hot gases known as plasma. The temperature of that gas reaches about 50 million degrees and glows in X-rays. Very little is known about how plasma moves, but scientists say that the discovery of its motion could be important in understanding how galaxy clusters form, evolve, and behave.

The scientist selected two nearby, massive, bright, and well-observed galaxy clusters, called perseus and coma. The team mapped out how the plasma moves, including whether it first went away from observers, speed, and so on. The team measured large areas of the sky, roughly the size of two full moons for purses and four for comas.

The team found direct signs of plasma flowing, splattering, and sloshing within the Perseus cluster. This type of motion was predicted, but this is the first time it has been observed. Because of what causes plasma to move in this way, scientists believe that small subsets of galaxies collide and merge with the main cluster. Those collisions are energetic enough to disrupt Perez's gravitational field and initiate sloshing motions that can last several millions of years. The coma does not have a sloshing plasma and appears to be composed of two major subsets that are slowly merging.
