Description

The influence of the plane gravitational wave on the CMB spectral distribution is studied. In the context of the kinematic SZ effect the distribution maximum is found to be shifted to the soft spectrum range due to the changes of the space-time metrics. The contribution of soft photons generated by charged particle in the field of a gravitational wave into the CMB is derived (the thermal SZ effect). We show that such a contribution leads to changing the CMB spectrum, broadening its shape.
