LAS General Meeting this month will be a talk by Chuck Keeton a faculty member of Rutgers University Department of Physics and Astronomy.
Through Gravity's Looking Glass
"A long time ago in a galaxy far, far away." That phrase made famous by Star Wars has become very real for astronomers. Because light takes time to reach us, looking out into the universe means literally looking back in time. Modern telescopes let us see almost all the way back to the age when stars and galaxies were just being born. But they need a boost from "cosmic telescopes" -- massive clusters of galaxies whose gravity bends light and magnifies our view of the distant universe. I will show examples of cosmic telescopes observed with the Hubble Space Telescope and discuss how we analyze the distortions and magnifications to study the first galaxies in the universe.
