The cosmic microwave background is the electromagnetic radiation that bathes the Universe as a whole, emitted when it was onlyaround380 000 yearsold. Buried beneath the strata of emissions from our own and distant galaxies, and distorted by large-scale concentrations of matter, this fossil radiation is a window onto the very beginnings of the Universe. In this presentation, we will discuss cosmic archaeology and the keys by which the deciphering of the cosmological background continues to nourish our understanding of the history of the Universe.
A CNRS researcher since 1999, Nabila Aghanim is an astrophysicist at the Orsay Institute of Space Astrophysics, specializing in observational cosmology. Her work, rewarded by two CNRS medals, aims to understand the origin and evolution of cosmic structures, and the constituents of the Universe, thanks to the cosmic microwave background and galaxy clusters.
