Physics Department Summer Lecture Series
"Using Gravitational Lensing to measure Dark Matter and Dark Energy in the Universe"
Presented by Erin Sheldon, BNL
Friday, June 28, 2019, 12:30 pm — Small Seminar Room, Bldg. 510
Gravitational lensing is the bending of the path of light near massive bodies. Mass produces a curvature of space time, and light follows a curved path that is calculable using the General Theory of Relativity. I will discuss how the lensing effect is used to measure the amount of Dark Matter in galaxies and in the universe as a whole. I will also discuss how we use lensing to measure the properties of the mysterious Dark Energy that is driving the accelerated expansion of our universe.
