May 11, 2005 - Looking at the Dark Side of the Universe - Henk Hoekstra, UVic Astronomy.

Gravetational LensingThe contents of the universe are dominated by two mysterious components: dark matter and dark energy. In both cases their existence has been inferred from astronomical observations. To learn more about the dark side of the universe I use nature's own weighing scales: gravitational lensing. Massive structures in the universe deflect the paths of photons passing near them. By measuring the amount of deflection (or a related quantity) we can infer the masses of such structures. This relatively new technique is rapidly gaining ground because of its unique sensitivity to dark matter, and more indirectly to dark energy. I will show some examples gravitational lensing and my research, which nowadays is driven by larger and larger data sets.
