Austin Peay State University Provost Lecture Series to discuss Earth’s atmosphere as a nuisance in astronomy

Austin Peay State UniversityClarksville, TN – The Earth’s atmosphere, though necessary to support life, is a major nuisance to accurate astronomical work. Instrumentation has improved over the past few decades to a point that the time-tested techniques to account for the effects of the atmosphere on astronomical data are no longer sufficient.

“With major new astronomical surveys beginning, advances in the techniques to account for the atmosphere are needed,” said Dr. J. Allyn Smith, associate professor of physics and astronomy.

Smith will discuss this topic in more detail as part of the next Provost Lecture Series session at APSU. He will speak at 3:00pm, Thursday, March 15th in the Morgan University Center, Room 307. The event is free and open to the public. The title of his talk is “The Earth’s Atmosphere, a Major Nuisance in Astronomy.”

Smith will look at a brief history of the field of photometry for the early days of the science to modern surveys and describe the methods used to account for  the effect of the atmospheric component in the data. He also will discuss the science needs for current surveys as the driver for these new techniques.

Smith earned a Ph.D., two Master of Science degrees and a bachelor’s degree all from the Florida Institute of Technology.
Formerly a visiting professor of physics and astronomy at the University of Wyoming, Smith has refereed nearly 100 publications and published several abstracts. He is recognized as an authority in large survey calibration and photometric standard star systems. He is currently involved in the Dark Energy Survey and the Large Synoptic Survey Telescope projects.

Prior to APSU, Smith was a space shuttle orbiter test conductor for Rockwell International Corp. and Lockheed Space Operations Co. at the Kennedy Space Center in Florida from 1982-92; a visiting professor of astronomy and physics at the University of Wyoming; and most recently a staff member at Los Alamos National Laboratory.

Other sessions in the Provost Lecture Series also are planned for the academic year. All sessions are from 3:00pm-4:30pm in the MUC, Room 303 (unless noted otherwise) and include the following:

March 22nd: Dr. Sharon Mabry, professor of music
March 29th: Dr. Cameron Sutt, assistant professor of history
April 5th: Mark DeYoung, assistant professor of art
April 12th: Dr. Tim Winters, professor of English
April 19th, MUC 103: Dr. Jeffrey Wood, professor of music

The Provost Lecture Series seeks to foster a spirit of intellectual and scholarly inquiry among faculty, staff and students. The program will be used as a platform for APSU faculty members who are recent recipients of provost summer grants, who have been awarded faculty development leaves and who have engaged in recent scholarly inquiry during sabbatical leaves.

APSU faculty members with recent research of acclaim also will be given a platform within this series. In addition, other faculty members of local or widespread renown will be invited to lecture within this series.
