Abstract/Description
Gravitational Lensing has become an integral part of astrophysics and the study of matter in the universe. In weak gravitational lensing, an object appears distorted when viewed from the observer’s perspective. This is caused by the bundle of light being distorted by an object of considerable mass. Because the distance to each part of this bundle is not the same, the rays of light are affected differently causing a shearing and magnification of the image. This alteration in the image we see can be modeled using the thin lens approximation. By integrating the equations for light travel based on general relativity, a more accurate model can be created. Over the summer of 2008, my mentor and I have worked on creating a program through this method. By coding numerous mathematical operations and rewriting existing code to support a new coordinate system we have created a full program.
