IRAM Grenoble

The New IRAM KID Array 2 (NIKA2) is a dual-band continuum camera operating at the IRAM 30m telescope on the Sierra Nevada, in Spain. It is equipped with three kilo-pixels arrays of Lumped Element Kinetic Inductance Detectors (LEKID) cooled at 150mK. NIKA2 observes simultaneously at 1.2 and 2.0 mm, and has polarimetry capabilities at 1.2 mm. I will introduce the NIKA2 instrument, its state of the art KIDs technology, its current performance and its bright future. I will then present the most recent science results: NIKA2 studies the magnetic fields of massive star forming regions and supernova remnants, the interplay between star formation and interstellar medium components in nearby galaxies, the structure of the intracluster medium in massive clusters of galaxies, and the evolution of the dust cosmic density all the way back to an epoch when the Universe was less than 1 Gyr old. Join me in this journey across the millimeter sky!
