Weak Gravitational Lensing: Because We're Stuck With Photons

Ms. Rebecca Sobel Levinson, MKI Graduate Student

Jan/14 Tue 02:00PM-02:30PM 37-252

Enrollment: Unlimited: No advance sign-up
Prereq: none

Most of the universe does not emit light. Dark matter outweighs baryonic matter in the universe approx. 5:1. So how do we learn about this dark universe when our primary tools for observing it require light?

Come learn about gravitational lensing, one of the tricks of astronomy that allows us to peer into the darkness of our universe. I will review the basics of gravitational lensing, and some of the neat things we can learn from it. I will then focus on weak lensing in clusters, the science behind some of the most beautiful Hubble images ever taken.

No enrollment limit, no advance sign up for the talk.  Please note that there is a tour of the Space Nanotechnology Lab from 3:15-4:15pm.  The tour is limited to 6 people. Prerequisite for the tour is attending this talk as well as the 2:30-3:00pm talk "High-resolution x-ray optics at the Space Nanotechnology Laboratory: From nanometers to gigaparsecs".
