PRISM: Recovery of the primordial spectrum from Planck data
F. Lanusse, P. Paykari, J. -L. Starck +3
The primordial power spectrum describes the initial perturbations that seeded the large-scale structure we observe today. It provides an indirect probe of inflation or other struct…
PRISM: Sparse recovery of the primordial spectrum from WMAP9 and Planck datasets
P. Paykari, F. Lanusse, J. -L. Starck +2
The primordial power spectrum is an indirect probe of inflation or other structure-formation mechanisms. We introduce a new method, named \textbf{PRISM}, to estimate this spectrum…
Sparse point-source removal for full-sky CMB experiments: application to WMAP 9-year data
F. C. Sureau, J. -L. Starck, J. Bobin +2
Missions such as WMAP or Planck measure full-sky fluctuations of the cosmic microwave background and foregrounds, among which bright compact source emissions cover a significant fr…
Planck CMB Anomalies: Astrophysical and Cosmological Secondary Effects and the Curse of Masking
A. Rassat, J. -L. Starck, P. Paykari +2
Large-scale anomalies have been reported in CMB data with both WMAP and Planck data. These could be due to foreground residuals and or systematic effects, though their confirmation…
PRISM: Sparse Recovery of the Primordial Power Spectrum
P. Paykari, F. Lanusse, J. -L. Starck +2
The primordial power spectrum describes the initial perturbations in the Universe which eventually grew into the large-scale structure we observe today, and thereby provides an ind…
Joint Planck and WMAP CMB Map Reconstruction
J. Bobin, F. Sureau, J. -L. Starck +2
We present a novel estimate of the cosmological microwave background (CMB) map by combining the two latest full-sky microwave surveys: WMAP nine-year and Planck PR1. The joint proc…
