Satellite galaxies that can be found by super-computer technology.
A model of advanced technologies that run on super computers belonging to the United States have revealed the existence of satellite galaxies around the Milky Way. When looking more concretely, there are tracks that indicate its presence. Now, the model was used to find the "best friend" another galaxy.
Some time ago, an astrophysicist suggests that giant spiral galaxies like the Milky Way galaxy have tens or even hundreds of companion, either a size too small and faint visible in the night sky.
Recently, scientists are increasingly evident statement. Small Magellanic Cloud (The Small Magellanic Clouds) and large Maggellan Clouds (The Large Magellanic Clouds) are two examples of dwarf galaxies orbiting the Milky Way.
But what makes the scientists interested in a smaller cosmic structures is that they have material that is darker.
Both dwarf galaxies were discovered by an expert from the National Energy Research Scientific Computing Center (NERSC) named dislike Chakrabarti. Scientists women used a number of super computers at NERSC to simulate row mathematical model for our galaxy and the surrounding materials.
With homemade technology model that, Chakrabarti successfully identified a large number of dark galaxies around the Milky Way. One of them, he said, lies opposite the side of the Earth in the Milky Way. The distance is about 300,000 light years from the galactic center. (1 light year = 10 trillion kilometers).
"Our approach has broad implications for many fields of physics and astronomy. He can not directly detect dark matter that the average is dominated by dwarf galaxies, planetary dynamics, and evolution of galaxies are influenced by the surrounding satellite galaxies," said Chakrabarti .
Previously, he had originally presented the simulation results this year in Seattle, at a meeting of the American Astronomical Society. The work was done while he was still a researcher at the University of California at Berkeley (UCB).
"Currently, I use my method to do the test gratvitasi theories that have been modified and plans to run simulations at NERSC," said Chakrabarti. Reportedly, he will be presenting the results of simulations in three dimensions.
Chakrabarti is currently an assistant professor of physics at Florida Atlantic University. "NERSC system really speed up my work. This system is a great resource," he concluded.
