We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross correlating all relevant large-scale galaxy data sets with the cosmic microwave background radiation map provided by the Wilkinson Microwave Anisotropy Probe. With these measurements, the overall ISW signal is detected at the $\ensuremath{\sim}4.5\ensuremath{\sigma}$ level. We also examine the cosmological implications of these measurements, particularly the dark energy equation of state $w$, its sound… 

The integrated Sachs–Wolfe effect in the AvERA cosmology

The recent AvERA cosmological simulation of R\'acz et al. (2017) has a $\Lambda \mathrm{CDM}$-like expansion history and removes the tension between local and Planck (cosmic microwave background)

Constraints on massive vector dark energy models from integrated Sachs-Wolfe-galaxy cross-correlations

The gravitational-wave event GW170817, together with the electromagnetic counterpart, shows that the speed of tensor perturbations ${c}_{T}$ on the cosmological background is very close to that of

Cross-correlating Planck with VST ATLAS LRGs: a new test for the ISW effect in the Southern hemisphere

The integrated Sachs–Wolfe (ISW) effect probes the late-time expansion history of the Universe, offering direct constraints on dark energy. Here, we present our measurements of the ISW signal at

Perturbation level interacting dark energy model and its consequence on late-time cosmological parameters

In the present paper, we study the capability of interacting dark energy model with pure momentum transfer in the dark sector to reconcile tensions between low redshift observations and cosmic

Late universe dynamics with scale-independent linear couplings in the dark sector

We explore the dynamics of cosmological models with two coupled dark components with energy densities ${\ensuremath{\rho}}_{A}$ and ${\ensuremath{\rho}}_{B}$ and constant equation of state (EOS)

Uniformity of Cosmic Microwave Background as a Non-Inflationary Geometrical Effect

The conventional $\Lambda$CDM cosmological model supplemented by the inflation concept describes the Universe very well. However, there are still a few concerns: new Planck data impose constraints on

Large-scale structure and integrated Sachs–Wolfe effect in decaying vacuum cosmology

The concordance particle creation model - a class of $\Lambda(t)$CDM cosmologies - is studied using large scale structure (LSS) formation, with particular attention to the integrated Sachs-Wolfe

The cross-correlation between 3D cosmic shear and the integrated Sachs-Wolfe effect

We present the first calculation of the cross-correlation between three-dimensional cosmic shear and the integrated Sachs-Wolfe (iSW) effect. Both signals are combined in a single formalism, which

Measuring dark energy with the integrated Sachs-Wolfe effect

I present to this conference our latest measurements of the integrated Sachs-Wolfe (ISW) effect. After a brief review of the reasons for which this effect arises and of the technique to detect it by


One of the physical features of a dark-energy-dominated universe is the integrated Sachs–Wolfe (ISW) effect on the cosmic microwave background (CMB) radiation, which gives us a direct observational
