Outline of Final Research Achievements

We have developed a new accurate method of shape measurement of background galaxies in the weak lensing analysis by large scale structure of the universe which is used to study dark energy observationaly. We have detected the dark matter subhalos in nearby galaxy clusters. We confirm that the measured statistical properties of the observed subhalos are consistent with the prediction by the structure formation scenario based on cold dark matter.
We have proposed a new method of measuring the dark energy property using a new type of the lensed image in galaxy cluster which is predicted by us and discovered in 2009. The method is based on the fact that the redshift of the source galaxy depends critically on the dark energy so that we can improve the accuracy of the measuremnt of dark energy by observing many GRAMORs. We have also studied the effect of large scale structure on the apparent luminosity of supernovae and found that the effect is used to put an upper bound on nueutrino mass
