| Outline of Final Research Achievements |
We have made following four major achievements: 1, Discovery of 13 gravitationally lensed quasar systems from the SDSS-III quasar catalogue. 2, Construction of the largest catalogue of physically associated quasar pairs and the measurement of clustering amplitude of the pairs. The measured clustering indicates the importance of the direct-interaction to stimulate the quasar activity. 3, Evaluation of effectiveness of the bispectrum measurements for the weak lensing field from the Subaru HSC survey. It is revealed that the amount of the cosmological information recovered by the bispectrum is equivalent with increasing the survey region with approximately 0.5 times larger area, over the power spectrum measurement only. 4, Development of a method to measure the velocity power spectrum for data with wide and complex survey geometry.
