Dark Matter revolves around heat up and Dwarf galaxies



The exact nature of dark matter is one of the hardest questions of physics, because it is difficult to identify and has many mysterious expressions in it. Now a team from the Surrey University, UK, has found that dark matter can be heated and can move around the Galaxy due to star formation.

Scientists investigating nearby dwarf galaxies were looking for evidence of dark matter – small and unstable galaxies that usually take place around the big galaxy like the Milky Way galaxy. In which we live. The challenge of finding dark metal is that it does not communicate with light, as it does in the other way, it ignores its presence with its gravitational effects.

The team took an approach to study the effects of star formation in dwarf galaxies. When your shape takes shape, it can produce strong solar winds that remove the gas and dust from the center wrist and remove gas and dust particles. This means that over time the galaxy has fewer mass in the heart, which affects its gravity. We know that black matter clusters in the center of the galaxies, so when the Dwarf galaxy loses its mass from their centers, scientists are able to see how the change in gravity affects the remaining black substances. Research has found that in these situations, the dark energy has been obtained and the process moved away from the center of the galaxy, which is called "dark matter heating" by scientists.

They looked at the dark matter in the middle of sixteen different dwarf galaxies, in which there were a variety of different teas formations. They saw that the galaxies that had closed the stars many years ago, had a high density of black objects in the galaxy, which still make stars. "The small Dwarf's centers have received significant correlation between the amount of dark mass and the amount of star formation in their lives," said Professor Justin Reid, chairman of the study and head of department Surrey University's Physics Physics in a statement. "The gloomy object on the starry dwarf centers 'seems to have been' hot and thrown out. ''

Dark metal responds to the flow of gas and borders away from the center of the galaxy and away from the center of the gaazzi center. Which Reed et al., University of Surrey
