Sunyaev-Zel'dovich Array

The Sunyaev-Zel'dovich Array (SZ Array or SZA) was an array of eight 3.5 meter microwave telescopes at Owens Valley Radio Observatory (OVRO), California, to investigate the Sunyaev-Zel'dovich effect (SZ effect) on the cosmic microwave background (CMB). It began operation in 2005 and completed its survey in 2007, after which the dishes were incorporated into CARMA, which has since been retired.
