Deep radio imaging by researchers in the Uni of Cape Town and Uni of the Western Cape, in S Africa revealed supermassive black holes in a region of the distant universe are all spinning out radio jets in the same direction – most likely a result of primordial mass fluctuations in the early universe. The new result is the discovery – for the first time – of an alignment of the jets of galaxies over a large volume of space, via a 3yr deep radio imaging survey of the radio waves coming from a region called ELAIS-N1 using the Giant Metrewave Radio Telescope (GMRT).
