曲がり角のポテンシャル Cosmic shear analysis using HSC data

相対性理論 不完全-What is weak lensing dark energy? Weak lensing has the advantage of being sensitive to the clustering of matter, which can potentially allow us to differentiate between dark energy and modified gravity. However, if the clustering of matter is not accurately measured, the uncertainty is propagated into the measurement of dark energy parameters. What is a shear in astronomy? Mathematics/astronomy

Cosmic shear, an effect of distortion of image of distant galaxies due to deflection of light by matter, as predicted by general relativity (see also gravitational lens) Shear mapping, a particular type of mapping in linear algebra, also called transvection.
