Cosmic Background Imager

The Cosmic Background Imager (CBI) is a special-purpose radio telescope designed to study the cosmic microwave background radiation from the early universe. It is located at an altitude of 5080 m (16,700 feet) in the Chilean Andes at the Chajnantor Observatory.

The CBI Project is a collaboration between the California Institute of Technology, the Canadian Institute for Theoretical Astrophysics, the University of Chicago, the National Radio Astronomy Observatory, the Max-Planck-Institut für Radioastronomie (Bonn), Oxford University, the University of Manchester, the Universidad de Chile, and the Universidad de Concepción. The project has been supported by funds from the National Science Foundation, the California Institute of Technology, Maxine and Ronald Linde, Cecil and Sally Drinkward, Barbara and Stanley Rawn Jr., Rochus Vogt, the Kavli Institute, and the Canadian Institute for Advanced Research.
