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; depending on which method is used. We investigated three separate approaches; which essentially cover all previous studies; and also break new ground. (i) We correlated the CMB with the Planck reconstructed gravitational lensing potential (for the first time). This detection was made using the lensing-induced bispectrum between the low-â; and high-â; temperature anisotropies; the correlation between lensing and the ISW effect has a significance close to 2.5σ. (ii) We cross-correlated with tracers of large-scale structure; which yielded a significance of about 3σ; based on a combination of radio (NVSS) and optical (SDSS) data. (iii) We used aperture photometry on stacked CMB fields at the locations of known large-scale structures; which yielded and confirms a 4σ signal; over a broader spectral range; when using a previously explored catalogue; but shows strong discrepancies in amplitude and scale when compared with expectations. More recent catalogues give more moderate results that range from negligible to 2.5σ at most; but have a more consistent scale and amplitude; the latter being still slightly higher than what is expected from numerical simulations within ΛCMD. Where they can be compared; these measurements are compatible with previous work using data from WMAP; where these scales have been mapped to the limits of cosmic variance. Planck's broader frequency coverage allows for better foreground cleaning and confirms that the signal is achromatic; which makes it preferable for ISW detection. As a final step we used tracers of large-scale structure to filter the CMB data; from which we present maps of the ISW temperature perturbation. These results provide complementary and independent evidence for the existence of a dark energy component that governs the currently accelerated expansion of the Universe. © 2014 ESO;
