Compressed convolution
F. Elsner, B. D. Wandelt
We introduce the concept of compressed convolution, a technique to convolve a given data set with a large number of non-orthogonal kernels. In typical applications our technique dr…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
Planck 2013 results. XV. CMB power spectra and likelihood
Planck collaboration, P. A. R. Ade, N. Aghanim +257
We present the Planck likelihood, a complete statistical description of the two-point correlation function of the CMB temperature fluctuations. We use this likelihood to derive the…
Optimal bispectrum estimator and simulations of the the CMB Lensing-ISW non-Gaussian signal
Anna Mangilli, Benjamin Wandelt, Franz Elsner +1
In this paper we present the tools to optimally extract the Lensing-Integrated Sachs Wolfe (L-ISW) bispectrum signal from future CMB data. We implement two different methods to sim…
Planck 2013 Results. XXIV. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +237
The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal bispectrum estimators, sep…
Planck 2013 results. XVI. Cosmological parameters
Planck Collaboration, P. A. R. Ade, N. Aghanim +261
We present the first results based on Planck measurements of the CMB temperature and lensing-potential power spectra. The Planck spectra at high multipoles are extremely well descr…
