Astronomers Kaunasskogo project (Sloan Digital Sky Survey) was the largest three-dimensional map of massive galaxies known black holes. The announcement can be found on the project website. Article with description published in the Astrophysical journal Supplement Series.



The map contains information on the status of a million galaxies and is the largest in the world (for comparison, another recently introduced map included descriptions 45 thousand galaxies). However, it is only one third of the information that will be contained in the final version by the end of the six-year Kaunasskogo project.

Each one marked on the map of the galaxy contains about a hundred billion stars. They range from 1 to 6 billion light-years from Earth. To find a three-dimensional map in the Universe, using the supplied video (because of the lack of software to view yourself map. In it the image of galaxies applied in the points corresponding to their three-dimensional position.

The distribution of galaxies in space is important for cosmology. Existing clots and rarefactions in the distribution of galaxies originated from fluctuations of the density of matter in the early Universe. According to the existing model of cosmogenesis, they were caused by acoustic waves baryons. These fluctuations, known by the relict radiation, scientists used as a standard of length to determine changes the geometry of the Universe.

Differences existing distribution of matter in space, which was observed in the early Universe will clarify the effect of dark energy and dark matter.
