Optimization of a 4th generation CMB space mission

Abstract : The Cosmic Microwave Background radiation is a rich and clean source of Cosmological information. Study of the CMB over the past few decades has led to the establishment of a “Standard Model” for Cosmology and constrained many of its principal parameters. It hasalso transformed the field into a highly data-driven domain.Currently, Inflation is the leading paradigm describing the earliest moments of our Universe. It predicts the generation of primordial matter density fluctuations and gravitational waves. The CMB polarisation carries the signature of these gravitational waves in the form of primordial “B-modes”. A future generation of CMB polarisation space mission is well suited to observe this signature of Inflation.This thesis focuses on optimising a future CMB space mission that will observe the B-modesignal for reaching a sensitivity of r = 0.001. Specifically, I study the optimisation of the scanning strategy and the impact of systematics on the quality of polarisation measurement
