- Physikalisches Kolloquium on “Cosmic Microwave Background as the Backlight: Mapping Hot Gas in the Universe with the Sunyaev-Zeldovich Effect” [15:15, 50+10]
- Abstract: The Cosmic Microwave Background (CMB) is the light from the fireball Universe with a black-body spectrum. As photons of the CMB travel for 13.8 billion years to reach us, they encounter interesting events in the Universe. One such event is an encounter with hot electrons in cosmic plasma, which Compton up-scatter CMB photons and distort the black-body spectrum. This so-called "Sunyaev-Zeldovich effect" (SZE) has been measured with high precision, yielding a full-sky map of hot gas in the Universe. In this colloquium we describe physics of the SZE as well as new results from the highest resolution imaging of SZE, what we learned from the full-sky map of hot gas and state-of-the-art computer simulations, and a future prospect.

- Abstract: The cosmic microwave background (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 generated in the early Universe. With the WMAP we have confirmed many of the key predictions of inflation including flatness and statistical homogeneity of our Universe, Gaussianity and adiabaticity of primordial density fluctuations, and a small but non-zero deviation from the scale-invariant spectrum of density fluctuations. Yet, 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 including both the vacuum and sourced contributions (i.e., left and right hands of Einstein's equation), the LiteBIRD proposal, as well as a sub-mm telescope in Chile called CCAT-prime that we are currently building.

- Abstract: How did the Universe begin? What is the Universe made of? Will the Universe end? If so, how? Remarkably, we can find answers to these questions by scientific means. The Universe was once in a hot and dense state, like a fireball. The light that filled the fireball Universe did not go away - they are still with us. We can collect this light, called the “cosmic microwave background”, to study in detail how the Universe began and evolved. The fate of the Universe is determined by the mysterious “dark energy” that occupies 70% of the energy of the Universe today. Understanding this may tell us that the Universe ends in a catastrophic state. In this lecture, we present the history, the latest results, and the future of the cosmic microwave background research, which will tell us how the Universe began and may end.

- Abstract: We describe two unique galaxy redshift surveys to map out the large-scale structure of the Universe from z=0.6 to 3.5. Both will use the prime focus of large-aperture telescopes for wide fields of view. One is HETDEX, the on-going survey on 10-m Hobby-Eberly Telescope in West Texas, and the other is PFS, the planned survey on 8.2-m Subaru Telescope in Hawaii. We use Lyman-alpha emitters (HETDEX) and [OII] emitters (PFS) for z=1.9-3.5 and 0.6-2.4, respectively. The HETDEX is a super unique, non-traditional survey: we use integral field unit spectrographs (IFUs) to do the first blind emission-line surveys in a cosmological volume, without pre-selecting objects by imaging surveys. The PFS will use the highly multiplexed robotic multi-object fibre spectrograph. We describe the motivation for the projects, science goals, survey designs, as well as the current status of the projects.

- Abstract: It has been widely assumed that detection of primordial gravitational waves from inflation in, for example, B-mode polarisation of the cosmic microwave background, immediately implies discovery of the quantum nature of spacetime. While this statement is true for the vacuum solution, it does not apply if the gravitational waves originate from the matter fields. How can we distinguish between these two origins? The answer is non-Gaussinaity. We show that the gravitational waves from SU(2) gauge fields coupled to a spectator axion field during inflation are highly non-Gaussian with a characteristic shape, whereas those from the vacuum are only weakly non-Gaussian.
