Final Activity Report Summary - CMB DATA ANALYSIS (Data analysis methods and tools for the next generation of the Cosmic Micorwave Background polarization experiments)
The studies of cosmic microwave background (CMB) anisotropies have been recognised as one of the most fruitful way of investigating the Universe, unveiling its composition, constraining the cosmological parameters as well as peering into the physics at the highest energy scales exceeding by many orders of magnitude those achievable in the present day man-made laboratories. The CMB potential can be however only unlocked if observational data gathered by ever growing in size and sophistication CMB experiments are analysed efficiently in a statistically robust way. The aim of this proposal was to develop statistically sound algorithms and numerical tools which would be useful in achieving such a goal. Its focus was on the methods of producing the maps of the sky in the microwave band, separating them into the maps of the sky signals of different physical origins, and thus effectively cleaning the primordial cosmological CMB signal and then estimating its statistical properties in particular its two point statistics described by its power spectrum. They all belong to key steps of data analysis pipelines of any CMB experiment. The work performed under the auspices of this proposal resulted in a number of efficient algorithms subsequently implemented in high performance software packages. These were then tested on the simulated data and made available to experimental teams working on a development of the next generation CMB polarisation experiments. The developed software tools are used by the data centres in France and Italy working to prepare the European satellite mission, Planck. They are also expected to become a backbone of the data analysis pipelines of EBEX and PolarBeaR - currently developed balloon-borne and ground-based observations, and are already used in their optimisation and design. The proposed techniques will be also useful in planning and optimisation of future CMB experiments.

Project objective
This proposal seeks funds to support research in the area of data analysis of Cosmic Microwave Background (CMB) data sets. The final purpose of the proposed project is to enable an efficient and comprehensive exploitation of the future CMB data sets and their potential to shed light on some of he most fundamental questions of the modern cosmology: the nature of dark energy, dark matter and inflation. To facilitate this goal we propose to develop a flexible, statistically robust and computationally efficient CMB data analysis pipeline capable of addressing needs of the future CMB polarization experiments. The produced pipeline is expected to be general and applicable to a broad class of scanning experiments. It will be based on novel data analysis methods, algorithms and software tools, which we plan to devlop in order to meet the goals set in this project. As a part of this work, we will apply the developed pipeline to some of the currently planned CMB polarization experiments to help with their optimization and design. We will also employ it to the analysis of the data sets produced by those experiments, once they become available. This proposal will support the relocation of Dr. R. Stompor back to Europe and will help him to develop this line of research at the APC institute in Paris.""
