Swiss hardware contribution to the Euclid mission
Ground data analysis contribution
The analysis of the Euclid data is an extremely challenging task due to the large volume and the complexity of the data. This task has been divided into a number of European consortia. The Science Working Groups (SWGs) are responsible for defining the requirements, the Organisational Units (OUs) are studying possible solutions by testing different algorithms and the Science Data Centers (SDCs) implement the software into operational frameworks. The SDCs will be in charge of the data processing after the launch (currently foreseen for 2019).
The Swiss Science Data Center (SDC-CH) is in charge of implementing software related to
- the determination of the distances of remote galaxies from the analysis of their colors (i.e., the photometric redshift),
- the characterization of the strong deformation observed when the light of remote galaxies goes trough a particularly large mass concentration (i.e., the so-called Strong lensing).
Other Swiss contributors include the Swiss Federal Institute of Technology of Lausanne (Euclid@EPFL), the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), the department of theoritical physics of the University of Geneva (UniGE theoretical physics) and the University of Zurich (UniZH).
