Non-Gaussianity and the CMB Bispectrum: confusion between Primordial and Lensing-Rees Sciama contribution?
Anna Mangilli, Licia Verde
We revisit the predictions for the expected Cosmic Microwave Background bispectrum signal from the primary-lensing-Rees-Sciama correlation; we point out that it can be a significan…
Isocurvature modes and Baryon Acoustic Oscillations II: gains from combining CMB and Large Scale Structure
Carmelita Carbone, Anna Mangilli, Licia Verde
We consider cosmological parameters estimation in the presence of a non-zero isocurvature contribution in the primordial perturbations. A previous analysis showed that even a tiny…
Dust moments: towards a new modelling of the galactic dust emission for CMB B-modes analysis
Anna Mangilli, Jonathan Aumont, Aditya Rotti +4
The characterization of the spectral energy distribution (SED) of dust emission has become a critical issue in the quest for primordial B-modes. The dust SED is often approximated…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An Extended White Paper
PRISM Collaboration, Philippe André, Carlo Baccigalupi +140
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Visio…
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…
CMB Polarization can constrain cosmology better than CMB temperature
Silvia Galli, Karim Benabed, François Bouchet +6
We demonstrate that for a cosmic variance limited experiment, CMB E polarization alone places stronger constraints on cosmological parameters than CMB temperature. For example, we…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): A White Paper on the Ultimate Polarimetric Spectro-Imaging of the Microwave and Far-Infrared Sky
PRISM Collaboration, Philippe Andre, Carlo Baccigalupi +101
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in response to the Call for White Papers for the definition of the L2 and L3 Missions in the ESA Sc…
Isocurvature modes and Baryon Acoustic Oscillations
Anna Mangilli, Licia Verde, Maria Beltran
The measurement of Baryonic Acoustic Oscillations from galaxy surveys is well known to be a robust and powerful tool to constrain dark energy. This method relies on the knowledge o…
Absolute calibration of the polarisation angle for future CMB -mode experiments from current and future measurements of the Crab nebula
Jonathan Aumont, Juan Francisco MacÃas-Pérez, Alessia Ritacco +2
A tremendous international effort is currently dedicated to observing the so-called -modes of the Cosmic Microwave Background (CMB) polarisation. At the unprecedented sensitivit…
