Planck intermediate results. XIII. Constraints on peculiar velocities
Planck Collaboration, P. A. R. Ade, N. Aghanim +182
Using \Planck\ data combined with the Meta Catalogue of X-ray detected Clusters of galaxies (MCXC), we address the study of peculiar motions by searching for evidence of the kineti…
Planck 2013 results. XIX. The integrated Sachs-Wolfe effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +245
Based on CMB maps from the 2013 Planck Mission data release, this paper presents the detection of the ISW effect, i.e., the correlation between the CMB and large-scale evolving gra…
Planck intermediate results. VIII. Filaments between interacting clusters
Planck Collaboration, P. A. R. Ade, N. Aghanim +208
About half of the baryons of the Universe are expected to be in the form of filaments of hot and low density intergalactic medium. Most of these baryons remain undetected even by t…
Planck intermediate results. X. Physics of the hot gas in the Coma cluster
Planck Collaboration, P. A. R. Ade, N. Aghanim +207
We present an analysis of Planck satellite data on the Coma Cluster observed via the Sunyaev-Zeldovich effect. Planck is able, for the first time, to detect SZ emission up to r ~ 3…
Planck Intermediate Results. V. Pressure profiles of galaxy clusters from the Sunyaev-Zeldovich effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +214
Taking advantage of the all-sky coverage and broad frequency range of the Planck satellite, we study the Sunyaev-Zeldovich (SZ) and pressure profiles of 62 nearby massive clusters…
Planck Intermediate Results. IV. The XMM-Newton validation programme for new Planck galaxy clusters
Planck Collaboration, P. A. R. Ade, N. Aghanim +191
We present the final results from the XMM-Newton validation follow-up of new Planck galaxy cluster candidates. We observed 15 new candidates, detected with signal-to-noise ratios b…
Planck intermediate results. III. The relation between galaxy cluster mass and Sunyaev-Zeldovich signal
Planck Collaboration, P. A. R. Ade, N. Aghanim +183
We examine the relation between the galaxy cluster mass M and Sunyaev-Zeldovich (SZ) effect signal D_A^2 Y for a sample of 19 objects for which weak lensing (WL) mass measurements…
Characterisation of the non-Gaussianity of radio and IR point-sources at CMB frequencies
F. Lacasa, N. Aghanim, M. Kunz +1
This study, using publicly available simulations, focuses on the characterisation of the non-Gaussianity produced by radio point sources and by infrared (IR) sources in the frequen…
Efficient cosmological parameter sampling using sparse grids
Mona Frommert, Dirk Pflueger, Thomas Riller +3
We present a novel method to significantly speed up cosmological parameter sampling. The method relies on constructing an interpolation of the CMB-log-likelihood based on sparse gr…
Reconstruction of signals with unknown spectra in information field theory with parameter uncertainty
Torsten Ensslin, Mona Frommert
The optimal reconstruction of cosmic metric perturbations and other signals requires knowledge of their power spectra and other parameters. If these are not known a priori, they ha…
The axis of evil - a polarization perspective
Mona Frommert, Torsten A. Ensslin
We search for an unusual alignment of the preferred axes of the quadrupole and octopole, the so-called axis of evil, in the CMB temperature and polarization data from WMAP. We use…
Ironing out primordial temperature fluctuations with polarisation: optimal detection of cosmic structure imprints
Mona Frommert, Torsten A. Ensslin
Secondary anisotropies of the cosmic microwave background (CMB) can be detected by using the cross-correlation between the large-scale structure (LSS) and the CMB temperature fluct…
Optimal ISW detection and joint likelihood for cosmological parameter estimation
Mona Frommert, Torsten A. Ensslin, Francisco S. Kitaura
We analyse the local variance effect in the standard method for detecting the integrated Sachs-Wolfe effect (ISW) via cross-correlating the cosmic microwave background (CMB) with t…
Information field theory for cosmological perturbation reconstruction and non-linear signal analysis
Torsten A. Ensslin, Mona Frommert, Francisco S. Kitaura
We develop information field theory (IFT) as a means of Bayesian inference on spatially distributed signals, the information fields. A didactical approach is attempted. Starting fr…
