The Sunyaev Zeldovic effect (also refered to as the SZ effect or Sunyaev Zeldovic theory) is the phenonomena that radiant cosmic microwave background radiation (CMB) interacting with "electron" clouds distorts the spectrum of the radiation. High energy of the negative particles cause photons to recieve energy. The CMB's isotropy, such that of a plasma state in all directions, increases this induction. When investigated, the Compton effect between the "photons" and the "electrons" alters the spectrum observed by the detectors. The plasmas of galaxies scatters the CMB and relatively distort the background spectrum, thus contributing to statistical uncertainties.

Sunyaev Zeldovic theory relies on the basis of:

Sunyaev & Zeldovich predicted the effect and conducted research in 1969, 1972, and 1980. The Sunyaev Zeldovic effect is a chief astrophysical and cosmological interest. Sunyaev Zeldovic theory will determine disk accretion and photon-electron scattering. The Sunyaev Zeldovic effect can also help determine the value of the Hubble constant and universal motion parameters.

Observed distortions of the microwave background spectrum are used to detect the of density perturbations of the universe. Using the Sunyaev Zeldovic theory, research on very large scale velocity fields have been done and future CMB detection experiments will have to account for the contributions from various mediums generated through the Sunyaev-Zeldovich effect. Current research is focused on the distinctive type of angular fluctuations from the Sunyaev Zeldovic Effect in the microwave background, due to plasma galaxy clusters redshifts, to measure the scale of the universe. Hydrodynamic structure formation experiments are being studied to gain data on thermal and kinetic effects in the theory. Observations are difficult due to the size of the effect and other discrete electromagnetic fluctuations.
