Title: Latest results from the Planck satellite and implications for star formation properties
Date (JST): Thu, Apr 30, 2015, 13:30 - 14:30
Place: Seminar Room A
Abstract: The Planck satellite has recently made the third public release of the CMB data and a series of publications show casing the scientific results about the early Universe and late-time cosmology from the large scale structures. For the first part of the talk, I will highlight some of the important topics from this release, including the constraints of cosmological parameters obtained from, e.g. CMB power spectrum and SZ galaxy clusters, measured from the Planck data. In the second part of the talk, I will present a new measurements of the Cosmic Infrared Background (CIB) anisotropies and its first likelihood using the highest frequency observations from Planck. We interpret the measured CIB anisotropies in the context of physical models for galaxy clustering and the evolution of infrared emission of galaxies, hence providing information of the star formation histories in galaxies out to high redshift (e.g. z 〜2).
