| Summary: | 碩士 === 國立臺灣大學 === 物理研究所 === 96 === For the light rays are deflected by dark matter engendering the gravitational lensing effect in the universe, the galaxies become deformed as we observe. Utilizing the measure of distortion, the variation of its ellipticity, is capable to estimate the mass of dark matter clusters. In this work, we investigate the accuracy of halo mass measurement through weak gravitational lensing, and the
lower bound of mass detection on the sky survey.
