Analysis weeks: One of us will be "on call" during each of the regular lab section times.

This course does not have an official textbook. However, you may find it useful (or just interesting!) to dip into Bracewell, The Fourier Transform and its Applications, Rohlfs & Wilson, Tools of Radio Astronomy, and Wall & Jenkins, Practical Statistics for Astronomers, all of which will be on reserve in SERC. The online Essential Radio Astronomy course developed by Jim Condon and Scott Ransom at the National Radio Astronomy Observatory is also an excellent reference.

Here's the official course catalog listing:
"Observational study of the solar system, stars, and galaxies, using the Serin 3 meter radio telescope. Emphasizes computer techniques for data reduction and analysis. Topics may include calibrating system properties, the variability of the Sun, Jupiter, or quasars, and mapping the distribution of hydrogen in our Milky Way galaxy and measuring its rotation."

I plan to teach this course so that by the end of it you will not only have experience acquiring and analyzing data from the (ahem) 2.3 meter telescope on the roof, but also an understanding of how astronomers use much larger (e.g., 100 meter) radio telescopes in their research, and what kinds of astronomical targets they observe.

Lectures: The sequence of lecture topics may be updated during the course of the semester. The last lecture is tentatively reserved for a topic related to radio astronomy to be chosen shortly after spring break by the students enrolled in the course. This will give you an opportunity to make me sweat, thus exacting revenge for a semester's worth of quizzes and lab reports.
Labs: There will be a total of six labs in this course. Each of the first four labs will involve one week of observations and one week of analysis, with lab reports due the following Monday in lecture. The fifth lab will involve analysis of an existing dataset taken with an array of radio telescopes. The sixth lab will involve either a final set of observations with the 2.3 meter telescope on the roof, or an observing trip to West Virginia.
NRAO trip: A class trip to the National Radio Astronomy Observatory's site in Green Bank, West Virginia has been arranged for the weekend of April 17-19. This will be a time-consuming trip (the drive alone takes 7-8 hours each way); however, it will give you a unique opportunity to see a research-grade observatory located in the center of the National Radio Quiet Zone, a variety of radio telescopes, and hands-on observing experience with a more powerful instrument than what we have available in New Jersey. Students who participate will be excused from the sixth lab.

Your course grade will be based on a combination of four elements:

Quizzes will be administered during lecture (beginning, middle, or end) without warning. While many of the labs will involve observations done in teams, you should write up your lab reports individually.
