Effect of peculiar velocities on the gravitational potential in cosmological models with perfect fluids
We consider a universe filled with perfect fluid with the constant equation of state parameter ω. In the theory of scalar perturbations, we study the effect of peculiar velocities on the gravitational potential. For radiation with ω=1/3, we obtain the expression for the gravitational potential in th...
