"Galaxies 10 billion years ago were making stars more actively than they do now," says Malhotra. "They usually also show more turbulence, likely because they are accumulating gas faster than a modern galaxy does. But here, we have cases of early galaxies that combine the 'calm' rotation of a modern one with the active star formation of their early peers. This suggests first that these galaxies have finished accumulating their gas, at least for now. But it also seems that turbulence is not actually required to trigger that early, active star formation."Read more at: http://phys.org/news/2014-04-young-galaxies.html#jCp
