Cosmic Microwave Background (CMB) is currently one of the most efficient probes of the early Universe. Among its keystone problems, there is an estimation of a signal from a very large noisy data. This represents a computationally challenging problem as the size of CMB datasets is expected to reach 10^{^15} in a near future.

We briefly discuss CMB data analysis, present two applications - map-making and parametric component separations - and focus on solvers and preconditioners for the arising linear algebraic systems.

This is a joint work with L. Grigori (Inria Paris) and R. Stompor (Universite Paris 7).
