Description
BISOU (Balloon Interferometer for Spectral Observations of the primordial Universe) is a CNES balloon-borne spectrometer designed to measure CMB spectral distortions. Its primary goal is the first detection of the CMB y-distortion monopole signal arising from the gravitation heating of gas during large-scale structure formation. BISOU should also measure the CIB and extragalactic CO monopoles, helping us to better understand the galaxie formation at cosmic noon. I will present the BISOU mission, its scientific objectives and instrument concept, together with the current status of the CNES Phase A study. In addition, I will discuss the preparation strategy that is put in place around the development of a laboratory breadboard.
