Title: New KIDs on the Sky, from NIKA to CONCERTO

　Speaker: Alexandre Beelen (Institut d'Astrophysique Spatiale)

　Location: Large conference room, 3rd floor

　Time:  1:30 PM,  March 29, 2018 (Thursday)

　Abstract: After quickly describing the basic principles of the new Kinetics Inductance Detectors (KIDs), used in the NIKA prototype instrument, I will make a short review of its main scientific results on Sunyaev-Zel'dovich (SZ) effect in galaxy clusters. In particular, the first detection of thermal and kinetic SZ emission in a galaxy cluster merger. I will then present the new NIKA2 instrument, opened to call for proposal since September 2017, and describe the Guaranteed Time Programs of the NIKA2 Consortium, with a focus on extra-galactic science, towards SZ effect in galaxy clusters and the Cosmological Legacy Survey. I will conclude by presenting CONCERTO, a new concept of instrument using KIDs,dedicated to Intensity Mapping of the C+ line at the epoch of re-ionization.
