Temperature Anisotropy of the CMBR and the Non-zero Cosmological Constant

Abstract

We analyze the effect of a spherically symmetric clump on the anisotropy of the cosmic microwave background radiation temperature in the framework of the standard model of cosmology with a non-zero cosmological constant $\Lambda$ and we show that it weakens the Rees-Sciama effect.
