    • TitleLiteBIRD - a satellite to find primordial gravitational waves from inflation in the Cosmic Microwave Background
    • AbstractThe 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 the current state of affairs regarding our understanding of the early Universe, physics of polarisation of CMB, and the LiteBIRD proposal.

  • 1/12: Give a talk on “Position-dependent Power Spectrum” [15:00-15:50] video
    • Abstract: How does the large-scale environment affect the growth of the small-scale structure? This seemingly simple question is connected directly to the three-point statistics, and we use cosmology as an example. Mode coupling of large and small scales contains information on non-linear gravitational evolution of cosmic density fluctuations, and the physics of the early universe that may generate such a coupling. Despite its importance in cosmology, progress on understanding mode coupling in the large-scale structure of the universe has been slow. In this talk, we present a novel idea called the "position-dependent power spectrum" and the associated "integrated bispectrum" to address the issue of mode coupling. Coupling of large and small scales makes two-point function of density depend on the environment, i.e., the long-wavelength perturbation. Correlating this locally-measured two-point function and the long-wavelength perturbation, we can measure the relevant three-point function without counting triplets, thereby greatly simplifying the analysis of the three-point function. Moreover, theoretical interpretation of these new statistics is straightforward, and can be cast in an elegant formalism called "separate universe picture". We present the basic idea, formulation, and its first application to the real observational data, reporting 7.4 sigma detection of the integrated bispectrum from the Sloan Digital Sky Survey III.
