PhD position in instrumentation for observational Cosmology in Paris
The precise characterization of the polarized fluctuations of the 3K Cosmic Microwave Background (CMB) appears today to be a major scientific challenge to further progress in the understanding of the primordial Universe. The so-called cosmological B modes in the CMB polarization are thought to have been generated by inflation in the very early Universe and would provide unique information about the origin of the Universe and fundamental laws of physics at very high energies. The weakness of the expected signals, a few nK for the B-Mode, requires a detection chain which must be highly sensitive together with an extreme immunity to instrumental systematic effects that are generally higher by a few orders of magnitude.
