- 題目:How to constrain "Dark Energy"? Measurements of the Expansion of the Universe with Supernova and Other Methods
要旨:One of the greatest mysteries in modern astrophysics is the observational fact that the expansion of the universe looks being accelerated by unknown energy source symbolically called "Dark Energy". In this talk, The method of measurements of the expansion using supernovae is shown, together with other methods measuring galaxy distributions, the cosmic microwave background, and gravitational lenses. Future prospects including efforts to improve the accuracy of the expansion measurement are presented.
