U of C Cosmologist To Give Talk on South Pole Telescope April 26

University of Chicago Cosmologist Tom Crawford will give a free astronomy talk entitled “Viewing the Edge of the Universe from the Bottom of the World: Science with the South Pole Telescope” on April 26 from 4:30 – 5:30 p.m. on the JJC Main Campus, 1215 Houbolt Road in Joliet.
 
Dr. Crawford’s talk will introduce attendees to the cosmic microwave background, the light that was emitted a few hundred thousand years after the Big Bang and is the oldest light in the universe. Because water vapor interferes with microwave observations, the best site on earth for viewing the cosmic microwave background is the driest, coldest place on earth: the South Pole.
 
Dr. Crawford will explain the vast scientific potential of cosmic microwave background observations and describe the motivation, design, and construction of the South Pole Telescope. His talk will include some observations on life at the bottom of the earth from his four trips to Antarctica. He will also highlight some of the recent exciting results from the South Pole Telescope.
 
The event will be held in D-2001. Admission is free, and the event is suitable for ages 6 and up. Refreshments will be available.
 
Dr. Crawford is a Senior Research Associate in the Department of Astronomy and Astrophysics and the Kavli Institute for Cosmological Physics at the University of Chicago. He has worked on the South Pole Telescope project full time since 2003. He participated in the design and construction of the telescope and receiver and now works on analyzing data from the South Pole Telescope.
