Observational Astronomy Laboratory

Catalog description

Basic observational astronomy techniques are introduced through observational exercises, lab experiments, lectures on relevant statistical techniques, and scientific writing assignments and review. ASTRO 320W Observational Astronomy Laboratory (3) will provide students with practical experience in basic observational and laboratory aspects of astronomical data collection and analysis, including an introduction to associated statistical concepts. Observational techniques will be introduced through an observing project using a telescope with a CCD imaging camera. Lectures will introduce fundamental principles including Poisson and Gaussian statistics, measurement precision, propagation of errors, systematic uncertainties, and basic scientific writing techniques. These principles will be put into practice in the observing project and the associated written reports, as well as with laboratory experiments and written reports investigating the properties of light and cosmic rays. Experiments include: a cosmic ray telescope; a Michelson interferometer; a photodiode and monochromator; laser interference, diffraction and refraction; fluorescent gases; and a diffraction grating spectrometer.
