QUBIC (QU Bolometric Interferometer for Cosmology) is an international project of experimental cosmology that aims to measure the B-mode in the polarization of microwave background radiation (CMB, for Cosmic Microwave Background), in order to discover what happened in the first moments after the birth of the Universe. Mode B of polarization would be related to primordial gravitational waves, predicted by the Inflationary Theory, a modification of the Big Bang Theory, which predicts an exponential expansion in the first moments of life of the Universe.
The project is carried out by an international collaboration that involves institutions from France, Italy, the United Kingdom, the United States and the Argentine Republic. Our country was chosen as the site of the first instrument, which will be located in the Alto Chorrillos area, Salta Province, at 4,900 meters above sea level – a site that will also house the Argentine-Brazilian radio telescope LLAMA (Large Latin American Millimiter Array) -. In this way, the Argentine Northwest will become a center of scientific attraction at a national, regional and global level.
