- 10/19: Ta-You Wu Distinguished Lecture on “Finding Cosmic Inflation” [video]
- Abstract: The Cosmic Microwave Background (CMB) gives a photographic image of the Universe when it was still an “infant”, and its detailed measurements have given us a wealth of information such as the composition and history 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 I will review the physics of CMB and key results from recent experiments, and discuss future prospects for quest to find out about our origins.

- 6/13: Give a talk on “Cosmic Birefringence” at the University of Tokyo.
- Abstract: Polarised light of the cosmic microwave background is sensitive to physics violating parity symmetry under inversion of spatial coordinates. In this presentation we report on a measurement of parity violation from polarisation data of two satellite missions, WMAP and Planck. The statistical significance of the measured signal is 3.6 sigma. If confirmed with higher statistical significance in the future, it would have important implications for the elusive nature of dark matter and dark energy.

GGI Tea Breaks’ Seminar on “Cosmic Birefringence” [video]
- 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 new measurements of parity violation, called “cosmic birefringence”, from polarisation data of the European Space Agency (ESA)’s Planck satellite. The statistical significance of the measured signal is about 3 sigma. If confirmed with higher statistical significance in future, it would have profound implications for the elusive nature of dark matter and dark energy.

Give a remote seminar on “Hunting for Parity-violating Physics in Polarisation of the Cosmic Microwave Background” for the Leung Center for Cosmology and Particle Astrophysics (LeCosPA), Taipei [video]
- 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 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. We also report on a new measurement from the latest Planck public data release 4.
This will be the first seminar talk to accounce our latest result on cosmic birefringence from Planck data release 4 (to appear in Physical Review Letters), along with a 25+5 min talk at the Recontres de Moriond delivered by Patricia Diego-Palazuelos (Univ. Cantabria) on Tuesday, January 25.
