We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400  deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven(More)
The two fundamental assumptions of the standard cosmological model — that the initial fluctuations are statistically isotropic and Gaussian — are rigorously tested using maps of the CMB anisotropy from the Planck satellite. The detailed results are based on studies of four independent estimates of the CMB that are compared to simulations using a fiducial(More)
Planck data have been used to provide stringent new constraints on cosmic strings and other defects. We describe forecasts of the CMB power spectrum induced by cosmic strings, calculating these from network models and simulations using line-of-sight Boltzmann solvers. We have studied Nambu-Goto cosmic strings, as well as field theory strings for which(More)

The new cosmic microwave background (CMB) temperature maps from Planck provide the highest-quality full-sky view of the surface of last scattering available to date. This allows us to detect possible departures from the standard model of a globally homogeneous and isotropic cosmol-ogy on the largest scales. We search for correlations induced by a possible(More)
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, i.e., the correlation between the CMB and large-scale evolving gravitational potentials. The significance of detection ranges from 2 to 4 σ, depending on which method is used. We investigate(More)
We update the all-sky Planck catalogue of 1227 clusters and cluster candidates (PSZ1) published in March 2013, derived from Sunyaev–Zeldovich (SZ) effect detections using the first 15.5 months of Planck satellite observations. addendum, we deliver an updated version of the PSZ1 catalogue, reporting the further confirmation of 86 Planck-discovered clusters.(More)
Short title Challenges and perspectives in the observation of CMB anisotropy 1 ABSTRACT Measurements of the cosmic microwave background (CMB) allow high precision observation of the Last Scattering Surface at redshift z ∼1100. After the success of the NASA satellite COBE, that in 1992 provided the first detection of the CMB anisotropy, results from many(More)
