Title：BISOU: towards the measurement of the CMB spectral distortions
Speaker: Prof. Bruno Maffei (Universit é Paris-Saclay)
Date/Time: 14:00-15:00, 10 th of Jul., 2024
Place: Collaboration room at Department of Physics
Abstract:
　The BISOU (Balloon Interferometer for Spectral Observations of the primordial Universe) project studies
the viability of a balloon borne spectrometer, pathfinder of a future space mission dedicated to the
measurements of the CMB spectral distortions. Taking into account the specificities of balloon flights, a
concept based on a Fourier Transform Spectrometer covering a spectral range from about 90 GHz to
2 THz is being studied and modelled. I will present the scientific goals, the instrument and payload
concept together with the results of this CNES phase 0 study evaluating the sensitivity of this project
to the CMB Compton y distortion and CIB measurements.
