Give a remote seminar on “Hunting for Parity-violating Physics in Polarisation of the Cosmic Microwave Background” for the Theoretical Particle Physics and Cosmology group at King’s College London.
Abstract: Polarised light of the cosmic microwave background, the remnant light of the Big Bang, is sensitive to parity-violating physics. In this presentation we report on a new measurement of parity violation from polarisation data of the European Space Agency (ESA)’s Planck satellite. The statistical significance of the measured signal is 2.4 sigma. If confirmed with higher statistical significance in future, it would have important implications for the elusive nature of dark matter and dark energy.

Give a remote colloquium on “Finding Gravitational Waves from the Early Universe” for the iTHEMS, RIKEN
Abstract: The Cosmic Microwave Background (CMB) gives a photographic image of the Universe when it was still an “infant”. We have been 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 period of the early Universe called cosmic inflation. While we have accumulated strong evidence for this picture, the extraordinary claim requires extraordinary evidence. The last prediction of inflation that is yet to be confirmed is the existence of primordial gravitational waves whose wavelength can be as big as billions of light years. To this end we have proposed to JAXA a new satellite mission called LiteBIRD, whose primary scientific goal is to find signatures of gravitational waves in the polarisation of the CMB. In this presentation we describe physics of gravitational waves from inflation, and the LiteBIRD proposal.

- 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? In this lecture 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.
