    July 15, 2012

    Nick Hand from the University of California, Berkeley and colleagues at the Atacama Cosmology Telescope (ACT) and the Baryon Oscillation Spectroscopic Survey (BOSS) were named by Physics World as one of the top 10 breakthroughs in 2012 for being the first to detect the large-scale motion of galaxy clusters. The motions of distant galaxy clusters tell us much about how the universe formed and sheds light on the mysterious dark matter and dark energy. Some 40 years ago, the Russian physicists Rashid Sunyaev and Yakov Zel'dovich discovered that this motion could be observed by measuring a slight temperature shift in…
