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 0h, 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)
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 study destriping as a map-making method for temperature-and-polarization data for cosmic microwave background observations. We present a particular implementation of destriping and study the residual error in output maps, using simulated data corresponding to the 70 GHz channel of the Planck satellite, but assuming idealized detector and beam properties.(More)

Planck has mapped the polarized dust emission over the whole sky, making it possible to trace the Galactic magnetic field structure that pervades the interstellar medium (ISM). We combine polarization data from Planck with rotation measure (RM) observations towards a massive star-forming region, the Rosette Nebula in the Monoceros molecular cloud, to study(More)

of both institutes for a pleasant working atmosphere. I am thankful to the Väisälä Foundation and Academy of Finland for their financial support, and CSC-Scientific Computing Ltd. for computational resources. I thank Prof. Kari Enqvist for his open-mindedness to accept me, who had no previous background in cosmology, to work in his Cosmology Group. I(More)
We examine eeects on primordial nucleosynthesis from a truly random spatial distribution in the baryon-to-photon ratio (). We generate stochastic uctuation spectra characterized by diierent spectral indices and root-mean-square uctuation amplitudes. For the rst time we explicitly calculate the eeects of baryon diiusion on the nucleosyn-thesis yields of such(More)
