Slice through the celestial equator showing the radial component of the velocity field (in kilometres per second). Blue regions are falling towards us and red regions are flying away from us. Galaxies of the Sloan Digital Sky Survey main galaxy sample are overplotted. In the centre of the slice, the infalling dynamics of the Sloan Great Wall, one of the largest structure of the known universe, can be observed. Credit: University of Portsmouth
New maps of dark matter dynamics in the Universe have been produced by a team of international cosmologists.Using advanced computer modelling techniques, the team has translated the distribution of galaxies into detailed maps of matter streams and velocities for the first time...
