Distortions of the spectrum of the cosmic background radiation.
Abstract
The interpretation of spectral distortions at all wavelengths, including the Rayleigh-Jeans deviations from the Planck law regarding the cosmic background radiation and the history of the early universe, the influence of Compton scattering of photons off electrons, and the production of photons by bremsstrahlung are considered, using the Kompaneets (1957) equation. The onset of heating for spectral distortion, turbulent heating, and dust and molecules at large redshift are discussed, and recent data at short (between 2.5 and 0.4 mm) wavelengths from the Berkeley group balloon experiment are analyzed.
