Planck intermediate results. XVI. Profile likelihoods for cosmological parameters
Planck Collaboration, P. A. R. Ade, N. Aghanim +180
We explore the 2013 Planck likelihood function with a high-precision multi-dimensional minimizer (Minuit). This allows a refinement of the Lambda-cdm best-fit solution with respect…
Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation
Planck Collaboration, P. A. R. Ade, N. Aghanim +238
We present new measurements of CIB anisotropies using Planck. Combining HFI data with IRAS, the angular auto- and cross frequency power spectrum is measured from 143 to 3000 GHz, a…
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…
Planck 2013 results. XXV. Searches for cosmic strings and other topological defects
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
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, calc…
Planck 2013 results. XVIII. Gravitational lensing-infrared background correlation
Planck Collaboration, P. A. R. Ade, N. Aghanim +223
The multi-frequency capability of the Planck satellite provides information both on the integrated history of star formation (via the cosmic infrared background, or CIB) and on the…
Planck 2013 results. XII. Component separation
Planck Collaboration, P. A. R. Ade, N. Aghanim +252
Planck has produced detailed all-sky observations over nine frequency bands between 30 and 857 GHz. These observations allow robust reconstruction of the primordial cosmic microwav…
