First measurement of the submillimetre Sunyaev-Zel'dovich effect
Abstract
We report the first detection of the Sunyaev-Zel'dovich increment on the cosmic microwave background (CMB) at submillimetre wavelengths in the direction of a cluster of galaxies.It was achieved towards the rich cluster Abell 2163, using the PRONAOS 2-metre stratospheric telescope. Together with data from the SuZIE, Diabolo, and ISO-PHT experiments, these measurements, for the first time, give a complete picture of the far-infrared to millimetre spectral energy distribution of the diffuse emission toward a cluster of galaxies. It clearly shows the positive and negative parts of the S.Z. effect and also a positive signal at short wavelengths that can be attributed to foreground dust in our galaxy.
