An unequivocal detection of the Sunyaev–Zeldovich effect1, the cooling of the brightness temperature of the microwave background radiation towards the atmospheres of clusters of galaxies, has profound cosmological significance2–6, but has hitherto proved elusive. We present here measurements of the effect towards three rich clusters of galaxies made with the 40-m telescope of the Owens Valley Radio Observatory at 20.3 GHz. These results are three times more sensitive than other results… Expand
