Non-Gaussianity of the Cosmic Infrared Background anisotropies II : Predictions of the bispectrum and constraints forecast
Aurélie Pénin, Fabien Lacasa, Nabila Aghanim
Using a full analytical computation of the bispectrum based on the halo model together with the halo occupation number, we derive the bispectrum of the cos- mic infrared background…
Non-Gaussianity of the Cosmic Infrared Background anisotropies I : Diagrammatic formalism and application to the angular bispectrum
Fabien Lacasa, Aurélie Pénin, Nabila Aghanim
We present the first halo model based description of the Cosmic Infrared Background (CIB) non-Gaussianity (NG) that is fully parametric. To this end, we introduce, for the first ti…
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. 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. 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. XXI. All-sky Compton parameter power spectrum and high-order statistics
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
We have constructed the first all-sky map of the thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored component separation algorithms to the 100 to 857 GHz freq…
