Discovery/HET Cosmology seminar: Jean-Luc Starck (CEA/Saclay)

Discovery/HET seminar by Jean-Luc Starck (CEA/Saclay).

Time and place: tuesday 11/3 @ 11.15 in Auditorium M

Title:
CMB map estimation from WMAP and Planck


Abstract: 
We present the first CMB map reconstructed from both WMAP and
Planck datasets. Using recent statistical tools based
on sparsity, we show that the Galactic barrier can be broken down, so that
we can have a full sky high quality CMB map, for the first time.
In addition, as a result of our novel approach, this high quality map is
free of any significant thermal SZ contamination.
Finally, we present a new method to reconstruct the primordial power
spectrum from WMAP-9yr data.

Looking forward to seeing you there.
