Thesis description In April 2024, the Simons Observatory’s (SO) [1] large aperture telescope will obtain its first light. This telescope, equipped with a 6m primary mirror and a focal plane…
We present constraints on cosmological parameters using maps from the last Planck data release (PR4). In particular, we detail an upgraded version of the cosmic microwave background likelihood, HiLLiPoP, based…
We present constraints on the tensor-to-scalar ratio r using a combination of BICEP/Keck 2018 and Planck PR4 data allowing us to fit for r consistently with the six parameters of…
Abstract: (IOP) The production of a primordial stochastic gravitational-wave (GW) background by processes occuring in the early Universe is expected in a broad range of models. Observing this background would…
