Title: Finding Gravitational Waves from the Early Universe
Abstract: The Cosmic Microwave Background (CMB) gives a photographic image of the Universe when it was still an “infant”. Its detailed measurements have given us a wealth of information such as the composition and history of the Universe. We are now using it to test our ideas about the origin of the Universe. The CMB research told us a remarkable story: the structure we see in our Universe such as galaxies, stars, planets, and eventually ourselves originated from tiny quantum fluctuations in the early Universe. But is this picture true? To answer this question, we are now trying to find a signature of the “primordial gravitational waves” generated from the earliest moment of the Universe in the polarised light of the CMB. In this colloquium, Eiichiro Komatsu will review the physics of CMB and key results from recent experiments, while discussing future prospects for quest to find out about our origins.
