Hamza’s paper is out !
Two B3DCMB papers accepted !
Two most recent papers, led by B3DCMB students, have been accepted for publication. The map-making paper by Hamza and collaborators, presents the MAPPRAISER software which implements state-of-the-art map-making methods based on novel, B3DCMB developed numerical solvers. The manuscript will be …
Map-making paper and software are out !
Hamza’s map-making paper is finally out ! Check it out on arXiv. The work led by Hamza is a result of a truly collaborative and multi-disciplinary effort. For us in the trenches this showcases the added value and usefulness of …
“Amended Gibbs samplers for for Cosmic Microwave Background power spectrum estimation” …
A new paper by Gabriel and co (including Nicolas, Josquin and Radek) just hit the shelves or at least on-line archive …
Please check here for more details … …
Clara gets her (scientific) spurs and a paper !
Clara Vergès – a graduate student associated with the B3DCMB project was awarded a title of a doctor of the newly created Université de Paris defending her …
New paper on accelerated solvers for CMB
Recently, Jan, Laura, and Radek submitted a paper proposing new techniques for solving a sequence of linear algebraic systems arising in time-domain component separation. The approach we have proposed combines: 1) two-level preconditioner where the second level is built progressively …

The paper by Giuseppe on “Iterative map-making with two-level preconditioning for polarized cosmic microwave background data sets. A worked example for ground-based experiments” (see Davide’s post here) has been just published (Puglisi et al, 2018, Astronomy & Astrophysics, …
New paper on linear solvers for the CMB data analysis
CMB data analysis commonly involves solution of large systems of equations. Finding appropriate solvers for these systems is a subject of ongoing research and one of the aims of B3DCMB project. The fact that, in general, the system matrix cannot …
One more step towards getting CMB maps in fewer steps
Cosmic microwave background (CMB) experiments chase faint signals from the primordial universe by continuously scanning the sky for years. Their cameras are typically read out hundreds of times per second, delivering the so-called time ordered data, which are nothing but …
