Introduction to Radio Astronomy for us Non-PhD People
Lisa Wray, Arecibo Observatory
Abstract:
In the early twentieth century, the field of radio astronomy emerged as
a result of a serendipitous discovery of cosmic "static" over long
distance telephone lines, and an amateur radio operator's dedication and
pioneering spirit. It was fostered by WWII radar technology and the
US-USSR space race. Prior to 1950, the science of astronomy was fiercely
protected by optical astronomers, but soon the opportunities for science
in the vast radio and microwave spectrum were accepted. This talk
introduces the engineering and briefly the science behind this sublime and
fascinating marriage of electrical engineering and astrophysics.
