The Gravitational Lensing model simulates the result of the deflection of photons as they pass through the warped space-time of a gravitational field of stars, clusters of galaxies or dark matter. In the simulation you can examine the effect caused by a gravitational lens in three different cases: 1. A point-mass lens and a point mass source. 2. A point-mass lens and an extended source. 3. A softened isothermal sphere lens and an extended source. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
The Gravitational Lensing model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_general_relativity_Gravitational_Lensing.jar file will run the program if Java is installed.
Please note that this resource requires
at least version 1.5 of Java (JRE).
