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… Expand

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)… Expand
Integrated Sachs-Wolfe effect in time varying vacuum model
The integrated Sachs-Wolfe (ISW) effect is an important implication for dark energy. In this paper, we have calculated the power spectrum of the ISW effect in the time varying vacuum cosmological… Expand
Galileon Gravity in Light of ISW, CMB, BAO and $H_0$ data
Cosmological models with Galileon gravity are an alternative to the standard $\Lambda {\rm CDM}$ paradigm with testable predictions at the level of its self-accelerating solutions for the expansion… Expand
Searching for Integrated Sachs-Wolfe Effect from Fermi-LAT Diffuse $\gamma$-ray Map
In this paper, we estimate the cross-correlation power spectra between the Planck 2018 cosmic microwave background (CMB) temperature anisotropy map and the unresolved $\gamma$-ray background (UGRB)… Expand
Updated tomographic analysis of the integrated Sachs-Wolfe effect and implications for dark energy
We derive updated constraints on the Integrated Sachs-Wolfe (ISW) effect through cross-correlation of the cosmic microwave background with galaxy surveys. We improve with respect to similar previous… Expand
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… Expand
Probing ΛCDM cosmology with the Evolutionary Map of the Universe survey
The Evolutionary Map of the Universe (EMU) is an all-sky survey in radio-continuum which uses the Australian SKA Pathfinder (ASKAP). Using galaxy angular power spectrum and the integrated Sachs-Wolfe… Expand
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… Expand
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)… Expand
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… Expand
