摘要

The gravitational lensing magnification or demagnification due to large-scale structures induces a scatter in peak magnitudes of high-redshift Type Ia supernovae (SNe Ia). The amplitude of the lensing dispersion strongly depends on that of density fluctuations characterized by the σ_8 parameter. Therefore the value of σ_8 is constrained by measuring the dispersion in the peak magnitudes. We examine how well SN Ia data will provide a constraint on the value of σ_8 using a likelihood analysis method. It is found that the number and quality of SN Ia data needed for placing a useful constraint on σ _8 is attain- able with the Next Generation Space Telescope.
