Spectrum of the Sunyaev-Zel'dovich effect for high electron temperatures
TLDR
In this article, the spectral shape of the Sunyaev-Zel'dovich effect in the cosmic background radiation was analyzed in detail, taking into account relativistic corrections for a hot electron gas.Abstract:
We analyse in detail the spectral shape of the Sunyaev-Zel'dovich effect in the cosmic background radiation, taking into account the relativistic corrections for a hot electron gas We calculate the displacement of the zero-signal frequency, which is especially informative in a new method for measuring the millimetric temperature of the background radiation; we also present a simple analytical expression, to be used to fit the experimental data in spectral measurements of the effect in very hot cluster gasesread more

Relativistic Corrections to the Sunyaev-Zeldovich Effect
TL;DR: In this article, an extension of the Kompaneets equation which allows relativistic effects to be included to any desired order is presented, which is expected to be very accurate over all regions of the cosmic microwave background spectrum for kBTe up to ~10 keV.

TL;DR: Current CMB data is used to set some preliminary constraints on the values of fundamental cosmological parameters Ω and Ho using the maximum likelihood technique and secondary anisotropies due to the Sunyaev-Zel’dovich effect are described.

TL;DR: In this article, it was shown that any injection of energy att>1010 sec (red shiftz <105) leads to deviation from an equilibrium spectrum, and that a period of neutral hydrogen in the evolution of the universe is unavoidable.

Distortion of the microwave background by a hot intergalactic medium
TL;DR: In this article, the distortion of the cosmic microwave background by a hot, optically thin intergalactic medium (IGM) is calculated using the full frequency redistribution function, and it is shown that even if the IGM produces all the cosmic X-ray background, it is not detectable in the present observational data.
