Radio Astronomy in the 21st Century
with Professor Chris De Pree

8 p.m.

A planetarium show and viewing with the observatory telescopes (weather permitting) will follow the lecture.
Doors open at 7:30 pm, lecture begins at 8:00 pm

Radio astronomy is a relatively new discipline. Optical telescopes have been around for hundreds of years, but radio telescopes were not first used to look at the universe until the early 20th century. Modern radio telescopes use "arrays" of many telescopes to increase their resolution and sensitivity. In this talk, De Pree will trace the early evolution of radio telescopes, and describe the accomplishments of some of the more recently constructed arrays, including the Very Large Array (VLA), dedicated in 1980 and upgraded in the early 2000's, and the Atacama Large Millimeter Array (ALMA), dedicated in 2013. What are the resources required to operate large radio telescopes, and what are some of their most compelling discoveries?

Chris De PreeChris De Pree is the Charles A. Dana Professor of Astronomy at Agnes Scott College in the Department of Physics & Astronomy. He received his BS in physics from Duke University (1988), and his PhD in physics from the University of North Carolina at Chapel Hill (1996). He has been at Agnes Scott College since 1996.

Professor De Pree hosts a monthly Open House series at Bradley Observatory on the campus of Agnes Scott College, where he is the director.

He has written and edited a number of popular science books, including Idiot’s Guides: The Cosmos (2014), The Complete Idiot’s Guide to Astronomy (4e, 2008), Physics Made Simple (2e, 2005), Recent Issues and Advances in Astronomy (2003) and The Van Nostrand Concise Encyclopedia of Science (2003).

Professor De Pree is a member of the American Astronomical Society (AAS), the American Association for the Advancement of Science (AAAS) and has a keen interest in issues involving science and society. He has published over 35 research articles in the areas of massive star formation and active galactic nuclei and has been awarded grants for his research by NASA and the National Science Foundation.
