Abstract
A cosmological model with dissipative redshift is analyzed. In this model the observed redshifts of galaxies in groups and clusters consist of a Doppler part and an additional (dissipative) term associated with differences in photon path lengths. The contribution to the redshifts from dissipation is estimated for models of galactic clusters with parameters similar to the observed characteristics of the Virgo and Coma clusters. It is shown that for these models the dissipative contribution is several times smaller than the contribution from the Doppler effect. Nevertheless, the effect is detectable when reliable, redshift independent estimates of the distances to probable members of galactic clusters are available and may serve as an independent test of the nature of the redshift of lines in the spectra of extragalactic objects.
