Records of Primordial Gravitational Waves in the Cosmic Microwave Background: Status, Challenges and Prospects for present and future CMB experiments

Abstract : We review the mechanisms leading to Gravitational Waves imprint in the Cosmic Microwave Background (CMB), the oldest light in our Universe that we can realistically see today. We discuss the current status of measurements, and the main challenges towards future precision measurements, focusing on the diffuse polarization emission from our own Galaxy. Finally, we outline the path ahead in terms of operating and planned CMB experiments.

About the speaker : Carlo Baccigalupi is Full Professor and Head of the Astrophysics Group at SISSA, Trieste, Italy. Previously he has worked for an extended period of time in the top universities of USA (Berkeley, Chicago, ...) and Europe (Heidelberg, London, Paris, ...) and played a leading role in planning large Cosmological Experiments concerning the Cosmic Microwave Background (Planck, PolarBear/Simons Array, Simons Observatory) and Large Scale Structure (Euclid) of our Universe. He is the author of hundreds of refereed papers in reputed scientific journals, and has been invited for lectures and seminars in many international conferences and schools.
