Description

In this talk I discuss interaction of the CMB photons with large scale magnetic field of cosmological origin. In the interaction process, light boson particles such as axion-like particles and gravitons can in principle be produced. The produced particles can in principle cause CMB temperature anisotropy and spectral distortions. Using COBE limits on spectral distortion parameters, constraints on axion-like parameter space are found. Spectral distortion due to graviton production are also discussed.
