Linear algebraic solvers in Cosmic Microwave Background data analysis

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).
