The origin of the clustering in the distribution of galaxies

Time goes from top to bottom. The "bullseyes" show where there have been two sources of pressure waves in the early universe, the waves travelling outwards like the ripples on a pond. Galaxies prefer to grow at the centre and edge of the bullseye. Their preferred separation is the radius of the bullseye (the scale bar). Image: Sam Moorefield, Swinburne University.
