We present the intensity foreground algorithms and model employed within the B eyond P lanck analysis framework. The B eyond P lanck analysis is aimed at integrating component separation and instrumental parameter sampling within a global framework, leading to complete end-to-end error propagation in the Planck Low Frequency Instrument (LFI) data analysis. Given the scope of the B eyond P lanck analysis, a limited set of data is included in the component separation process, leading to… 

Improved Gibbs samplers for cosmic microwave background power spectrum estimation

One of the proposed approaches, referred to as Centered over Relax, which capitalizes on additional, auxiliary variables to minimize computational time needed per sample, and uses overrelaxation to decorrelate subsequent samples, performs better than the standard Gibbs sampler by a factor between one and two orders of magnitude in the nearly full-sky, satellite-like cases.

An Introduction to the Conjugate Gradient Method Without the Agonizing Pain

The Conjugate Gradient Method is the most prominent iterative method for solving sparse systems of linear equations. Unfortunately, many textbook treatments of the topic are written so that even

Astrophysics Source Code Library

The editors of the AsCL and members of its Advisory Committee were on hand at a demonstration table in the ADASS poster room to present the ASCL, accept code submissions, show how the ASLI is starting to be used by the astrophysics community, and take questions on and suggestions for improving the resource.
