During 2019, IFAE has been supporting LAM in the integration and testing of the FWA inside the NISP system. Tests have been progressing well and it is expected that the NISP instrument is delivered for integration inside the Euclid satellite during 2020.
On the other front, the group has started activities inside the Euclid consortium to exploit the data and contribute to the scientific output of the mission. The activities have been more focused in the analysis of the PAU data with Machine Learning techniques, where we have made studies on star-galaxy separation, background prediction and Photometric redshift measurements with deep learning techniques. We have also joined the new Machine Learning Working group in Euclid to start exporting these techniques to this survey.
ASTEROID is an H2020 project aiming at enabling Europe to acquire the technology and knowledge necessary to manufacture 2k^2 high performance Infrared Focal Plane Arrays, define the types of products to design and define the strategy to create an industrial manufacturing line of these detectors. IFAE is partnering with companies and institutions in France and Austria to develop a low noise and low dark current detector that will be directly useful for astronomy application in both ground telescopes (ESO) or space telescopes (ESA).
IFAE’s responsibility is in the optical and electrical characterisation of the detector. During 2019, we have commissioned the equipment used and modified for Euclid GSE to perform the thermal cycles needed in the controlled and secured way. At the same we have also integrated all the optical elements needed for the detector characterisation. The European Southern Observatory (ESO) New Generation Controller (NGC) for the test of the Infrared Sensors is expected delivery during 2020, as well as the detectors from Lynred.
This project will allow IFAE to acquire the know-how in characterizing IR sensors for Astronomy and Space and establishes a possible link of future collaboration with other ESO missions and their world-class telescopes located in the Atacama Desert in Chile.
