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…
3D galaxy clustering with future wide-field surveys: Advantages of a spherical Fourier-Bessel analysis
F. Lanusse, A. Rassat, J. -L. Starck
Upcoming spectroscopic galaxy surveys are extremely promising to help in addressing the major challenges of cosmology, in particular in understanding the nature of the dark univers…
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…
