Mini Galaxies

A model of advanced technologies that run on super computers belonging to the U.S. have revealed the presence of satellite galaxies around the Milky Way. When looking for a more real, there is a trail that shows its presence. Now, the model used to find the "friend" of other galaxies.

Some time ago, an astrophysicist suggests that giant spiral galaxies like the Milky Way galaxy have dozens or even hundreds of companion, either a size too small and faint visible in the night sky.

More 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.

However, what makes scientists interested in the 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 joy Chakrabarti. Women scientists is using a number of super computers at NERSC to a row of a mathematical model to simulate our galaxy and the surrounding materials.

With this model it is homemade technology, 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-matter that the average is dominated by dwarf galaxies, planetary dynamics, and evolution of galaxies is affected by the satellite galaxies around it," said Chakrabarti .

Previously, he had originally presented the simulation results of this year in Seattle, at a meeting of the American Astronomical Society. The work was done while he was a researcher at the University of California at Berkeley (UCB).

"Currently, I use my method to test theories that have been modified gratvitasi and plans to run the simulation 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 accelerate my work. This system is a great resource," he concluded
