Ripples in Cosmic Web Measured Using Rare Double Quasars

press release 27th April 2017

Astronomers have made the first measurements of small-scale fluctuations in the cosmic web just 2 billion years after the Big Bang. These measurements were enabled by a novel technique using pairs of quasars to probe the cosmic web along adjacent, closely separated lines of sight.      Read more...
