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 …
A Julia crash-course !
A first installment of a crash, kick-off course in Julia, for (mostly) accomplished Python programmers stimulated by the B3DCMB project was held on March 11. The course is geared up towards the B3DCMB students and collaborators from APC and elsewhere …
Results of the B3DCMB project during SIAM CSE19
Some of our results and ideas concerning preconditioners and linear solvers were recently presented during SIAM Conference on Computational Science and Engineering in Spokane. Within the minisyposium organized by the NLAFET consortium (that includes a part of Laura Grigori’s team), …

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 …
