An international team of astronomers has prepared new maps of the dynamics of dark matter in space. With the help of computer models, they were able to distribute the galaxies in the form of detailed flows of matter with a speed mark.
A slice of the celestial equator showing the radial component of the velocity field (km / s). The blue areas move towards us, and the red areas move away. In the center, the dynamics of the Great Wall of Sloan is noticeable - one of the largest ecumenical structures.
Dark matter is still a mysterious substance, occupying more than 80% of the total universal mass. It does not react to light in any way, therefore it is still necessary to find out about evolution and distribution. To create used data Sloanovsky digital sky survey for 2000-2008. This set of color images 1/5 of the sky and the spectra of 900,000 galaxies.
New maps show the North Sky up to 600 Mpc. Scientists used tools to analyze the phase space and based on research since 2015.
