    • Abstract: かつて、宇宙は灼熱の火の玉であった。灼熱の宇宙を満たしていた光は消え去ることなく、今も宇宙を満たしている。この光の波長は宇宙膨張によってマイクロ波まで引き延ばされており、 宇宙マイクロ波背景放射(CMB)と呼ばれている。CMBの詳細な測定と最新の理論計算とを比べると、宇宙の組成や進化に関する情報を得られる。これまでの研究により、銀河、星、惑星などの宇宙の構造は、初期宇宙の小さな量子力学的揺らぎから生まれたという驚くべき結論に至った。しかし、これは真実なのだろうか？　本講演では、CMBの物理学と最近の観測から得られた主要な結果を概観し、我々の起源を探るCMBの研究の今後の展望について述べる。

  • 11/10: Give a talk on "Parity Violation in Cosmology: Does the Universe distinguish between left and right?"
    • Abstract: Copernicus showed that there is no special place in the Universe. Taking this further, we ask, “Is there a special handedness in the Universe?”, the question of parity symmetry. Parity symmetry is known to be violated in the weak interaction. Do the physical laws behind the unsolved problems of modern cosmology - cosmic inflation, dark matter, and dark energy - also violate parity symmetry? In this talk, we will discuss theoretical and observational possibilities of parity violation in cosmology, a topic that has received much attention in recent years.

  • 1/31: MUC(15:55)-EWR(19:05)
  • 2/3: Give a CCA colloquium on “The Temperature of Hot Gas in the Universe” [video]
    • Abstract: How hot is the Universe today? How hot was it before? In this talk, we report on the result of the observational determination of the mean temperature of hot gas in the Universe. We find that the mean gas temperature has increased ten times over the last 8 billion years, to reach about 2 million Kelvin today. As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized. We therefore expect a connection between the mean gravitational potential energy of collapsed halos and the mean thermal energy of baryons. Our result provides quantitative verification of such a connection via cosmic shock-heating.

  • 1/27: Give a colloquium of Graduiertenkolleg 2149 on “Cosmic Birefringence: A New Probe of Dark Matter and Dark Energy” 
    • 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.
