Study of the Experimental Probe of Inflationary Cosmology (EPIC)-Intemediate Mission for NASA's Einstein Inflation Probe (2009)

Bock, James, Aljabri, Abdullah, Amblard, Alex, Baumann, Daniel, Betoule, Marc, Chui, Talso, ...

Measurements of Cosmic Microwave Background (CMB) anisotropy have served as the best experimental probe of the early universe to date. The inflationary paradigm, inspired in part by the extreme...

Measuring the tensor to scalar ratio from CMB B-modes in presence of foregrounds (2009)

Betoule, Marc, Pierpaoli, E., Delabrouille, J., Jeune, M. Le, Cardoso, Jean-François

Abreg: We investigate the impact of polarized foreground emission on the performances of future CMB experiments in measuring the tensor-to-scalar ratio r. We design a component separation pipeline,...

Component separation with flexible models. Application to the separation of astrophysical emissions (2008)

Cardoso, Jean-Francois, Martin, Maude, Delabrouille, Jacques, Betoule, Marc, Patanchon, Guillaume

This paper offers a new point of view on component separation, based on a model of additive components which enjoys a much greater flexibility than more traditional linear component models. This...
