QUBIC Project


With the presence of national (MINCYT), provincial (Ministry of Education, Culture, Science and Technology of Salta), municipal authorities, the presidents of the CNEA and CONICET, members of the community of San Antonio de los Cobres and the International Collaboration at QUBIC, the QUBIC Observatory was inaugurated with great success. November 23 was a day of great emotion for all those present

After an intense week of work to integrate and test the instrument and its subsystems in Alto Chorrillos, QUBIC was installed on the observation mount, inside its shelter.

On October 16, 2022, after a trip in which all precautions were taken and the recommendations for transporting the equipment to Alto Chorrillos were followed, the instrument arrived at its final destination. As of October 17, the integration of the mount and the instrument in its shelter will begin.

The tests of the instrument performance in the Laboratory of Integration in CNEA-RNO,  Salta,  between July and August 2022 were very successful

The first astronomical object observed by QUBIC was the Moon. A predicted FWHM of 1 degree was confirmed, as can be seen in the image. A great achievement for the Collaboration!


After several months of hard work, the shelter and dome for QUBIC are ready to  receive the instrument in Alto Chorrillos

The inauguration of QUBIC Observatory will be
in November 23, 2022 (Agenda)


QUBIC (Q-U 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, Ireland, 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.
