The Multi-Wavelength Cosmology team (COSMO-ML) has a long-standing commitment to observational and instrumental cosmology. Since participating in the construction and analysis of data from the Archeops balloon in 1998, and then from the Planck satellite from 2000 onwards, the team's guiding principle has always been to be involved from the construction of the instruments through to the exploitation of the data for cosmology. The team's activities are divided into three parts.
The first concerns instrumentation, in close collaboration with the LPSC's technical services, in particular the design and electronics of detectors and cameras for cosmology. In particular, the team has acquired expertise in the development of instruments using KID (Kinetic Inductance Detectors) technology, as part of the Grenoble synergy in this area, which has led to the creation of the GIS KIDs. The second component of the team is data analysis, with the development of analysis pipelines, calibration, commissioning and performance characterisation of new experiments. This activity has led team members to play major roles in international collaborations (Planck, NIKA2, Concerto, Euclid). In particular, analysis of the raw data from these detectors is a key factor in controlling systematic effects, which is critical to the success of scientific exploitation. Finally, the third aspect concerns the analysis of higher-level data to obtain cosmological results. Over the years, the team has made significant contributions to experiments measuring the cosmic microwave background (CMB) in temperature and polarisation, the reconstruction of the gravitational lensing effect on the CMB and the measurement of the Sunyaev-Zeldovich (SZ) effect, as well as cosmology with galaxy clusters.
