It has large-field-of-view and operates in the range between 130 &#8211; 310 GHz. CONCERTO\u2019s Principal Investigator is Guilaine Lagache from the <a href=\"https:\/\/www.lam.fr\/?lang=fr\" target=\"_blank\" rel=\"noreferrer noopener\">Laboratoire d\u2019Astrophysique de Marseille<\/a> (France) and the Instrument Scientist is Alessandro Monfardini from <a href=\"https:\/\/neel.cnrs.fr\/\" target=\"_blank\" rel=\"noreferrer noopener\">Institut N\u00e9el <\/a>(France).<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The two main scientific goals of CONCERTO are a [CII]-intensity mapping survey and the observation of galaxy clusters. The <em>line intensity mapping<\/em> technique, applied to integrated emission from unresolved galaxies or gas clouds provides an observational window to measure the large-scale properties of structures in the Universe. Finally, the study of these structures will help scientist to have a better understanding about the physical processes that drive galaxy formation and evolution.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<p>The instrument installation started in late March 2021. It sits now onboard APEX inside the Cassegrain cabin. After a period of technical verification, CONCERTO produced the first test images of the Cat&#8217;s Paw nebula and the Crab Nebula (see <a rel=\"noreferrer noopener\" href=\"https:\/\/www.eso.org\/public\/announcements\/ann21010\/\" target=\"_blank\">ESO announcement<\/a>).
