Nettet1. mai 2005 · In this work, we propose to study the integrated Sachs–Wolfe (ISW) effect in IDMDE models. Regarding this, we initially introduce a theoretical framework for IDMDE models. Moreover, we briefly discuss the stability conditions of IDMDE models, and by specifying a simple functional form for the energy density transfer rate, we calculate the … NettetThe integrated Sachs-Wolfe effect. Based on cosmic microwave background (CMB) maps from the 2013 Planck Mission data release, this paper presents the detection of the integrated Sachs-Wolfe (ISW) effect, that is, the correlation between the CMB and large-scale evolving gravitational potentials. The significance of detection ranges from 2 to 4σ ... NettetThe ISW effect (Sachs & Wolfe ) is a secondary source of temperature anisotropy which is produced whenever the gravitational potentials Φ and Ψ are evolving in time, generating temperature anisotropies of the form 1 ceramic pro markham
