Planck 2015 results. XII. Full Focal Plane simulations
Planck Collaboration, P. A. R. Ade, N. Aghanim +228
We present the 8th Full Focal Plane simulation set (FFP8), deployed in support of the Planck 2015 results. FFP8 consists of 10 fiducial mission realizations reduced to 18144 maps,…
Planck 2013 results. XXXI. Consistency of the Planck data
Planck Collaboration, P. A. R. Ade, M. Arnaud +180
The Planck design and scanning strategy provide many levels of redundancy that can be exploited to provide tests of internal consistency. One of the most important is the compariso…
Planck 2015 results. XVI. Isotropy and statistics of the CMB
Planck Collaboration, P. A. R. Ade, N. Aghanim +242
We test the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite. Our results are based mainly…
Planck 2015 results. IX. Diffuse component separation: CMB maps
Planck Collaboration, R. Adam, P. A. R. Ade +236
We present foreground-reduced CMB maps derived from the full Planck data set in both temperature and polarization. Compared to the corresponding Planck 2013 temperature sky maps, t…
Planck 2015 results. XVII. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +239
The Planck full mission cosmic microwave background(CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity(NG). Using three…
Planck 2015 results. II. Low Frequency Instrument data processing
Planck Collaboration, P. A. R. Ade, N. Aghanim +213
We present an updated description of the Planck Low Frequency Instrument (LFI) data processing pipeline, associated with the 2015 data release. We point out the places where our re…
Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
Planck Collaboration, R. Adam, P. A. R. Ade +230
The polarized thermal emission from Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 1…
Planck 2013 results. XVII. Gravitational lensing by large-scale structure
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
On the arcminute angular scales probed by Planck, the CMB anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this effect, detecting len…
Planck 2013 results. IX. HFI spectral response
Planck Collaboration, P. A. R. Ade, N. Aghanim +217
The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment pri…
Planck 2013 results. III. LFI systematic uncertainties
Planck Collaboration, N. Aghanim, C. Armitage-Caplan +217
We present the current estimate of instrumental and systematic effect uncertainties for the Planck-Low Frequency Instrument relevant to the first release of the Planck cosmological…
Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Constraining topology in harmonic space
M. Kunz, N. Aghanim, L. Cayon +3
We consider several ways to test for topology directly in harmonic space by comparing the measured a_lm with the expected correlation matrices. Two tests are of a frequentist natur…
Non-Gaussianity: Comparing wavelet and Fourier based methods
N. Aghanim, M. Kunz, P. G. Castro +1
In the context of the present and future Cosmic Microwave Background (CMB) experiments, going beyond the information provided by the power spectrum has become necessary in order to…
Using the COBE/DMR data as a test-bed for normality assessments
N. Aghanim, O. Forni, F. R. Bouchet
A very important property of a statistical distribution is to know whether it obeys Gaussian statistics or not. On the one hand, it is of paramount importance in the context of CMB…
Searching for non-gaussianity: Statistical tests
O. Forni, N. Aghanim
Non-gaussianity represents the statistical signature of physical processes such as turbulence. It can also be used as a powerful tool to discriminate between competing cosmological…
