Ali Shakir Aims to Shine Light on Gravitational Lensing

91视频 student Ali Shakir is working to correct an error in how cosmologists measure intrinsic galaxy alignments. When viewing faint galaxy images, researchers have to factor in distortions such as when a distribution of matter — like a cluster of galaxies — has a gravitational field that bends the light of a distant source as it travels toward an observer. The phenomenon is known as gravitational lensing.
