Compared to the previous algorithms, our algorithm is much suitable for reconstructing a complex gravitational potential and a source with a complex surface brightness distribution. We applied our new algorithm to the image of a lensed quasar that we observed with the ALMA telescope. Then we found that the measured amplitude of fluctuations of matter density is too large if only subhaloes in the lensing galaxy are taken into account. We also developed a new tool for detecting gravitational lenses. We discovered many candidates of gravitational lenses in the HSC galaxy catalogue.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(B);
