The BOOMERANG project is supported by NASA, the National Science Foundation and the Department of Energy in the United States; by the Italian Space Agency, the Italian Antarctic Research Programme and the University of Rome La Sapienza in Italy; and by the Particle Physics and Astronomy Research Council in the United Kingdom.
