What does Planck tell us about inflation? - and beyond -

概要
The scattering of cosmic microwave background radiation (CMB) in galaxy clusters induces a polarization signal according to the quadrupole anisotropy of the photon distribution at the location of the cluster. This "remote quadrupole" derived from measurements of the induced polarization provides an opportunity to reconstruct primordial fluctuations on large scales. By comparing the local quadrupole of the CMB predicted by the primordial fluctuations reconstructed in this way with direct observations by CMB satellites, we discuss how the dark energy can be tested by CMB observations beyond the indefinite nature of the cosmic variance.

What does Planck tell us about inflation? - and beyond -

概要
Recent precise CMB measurements, such as Planck and BICEP/Keck, have given us a deeper understanding of cosmic inflation. In fact, conventional simple models (e.g., proposed in the early '80s) are in tension. In this talk, I would like to give a brief review of inflation, in particular, introduce how to classify the slow-roll inflationary models on the ns-r plane. I would also like to talk with you about what to expect in the future.

Dreaming for making an elaborate time lapse of LSS formation: CMB-lensing tomography to the beginning of the Universe

概要
Gravitational lensing has been a remarkable observational tool for over the past century, providing insights into gravitational physics through its relativistic and geometric signatures. Meanwhile, the large-scale structure (LSS) of the Universe encapsulates the dynamic interplay between gravitational infall and cosmic expansion. Recent literature of cosmology has drawn the attention to utilise gravitational lensing of the cosmic microwave background (CMB lensing), sourced by LSS, to reveal the detailed evolutionary history of cosmic structures, especially during their early formation stages at high redshifts (z > 1).In this seminar, we will introduce the concept of "CMB-lensing tomography," a method that employs angular two-point correlation statistics measured across distinct redshift slices. We will outline a strategic programme aimed at achieving precise CMB-lensing tomography at high redshifts. To the last minutes, we will illustrate this methodology using recent observations of Lyman-break galaxies obtained with the Subaru Telescope.
