The Interferometric Sunyaev-Zel'dovich Effect Imaging Experiment use the signatures which galaxy clusters leave in the cosmic microwave background to measure the age and geometry of our universe and to better understand the formation of massive structures. Our success hinges upon the development of sensitive cm-wave receivers which we've employed at the OVRO and BIMA radio observatories, and upon the features of interferometry.

Follow the links below to learn more about the Sunyaev-Zel'dovich Effect, our Imaging Experiment, and the Sunyaev-Zel'dovich Array (SZA) which we are currently building. The SZA is a array of eight 3.5 m telescopes operating at 26 - 36 GHz and 85 - 115 GHz dedicated to carrying out a survey for the SZE signatures of clusters, as well as detailed follow up images of the survey yield. The SZA will enable us to directly observe galaxy clusters from the moment of their formation.
