Physics 2060/4060

Observational Astronomy

 

Course Description

This course will serve as an introduction to the tools and techniques used in optical and radio astronomy. Using the facilities at the University of Utah Observatory , we will explore the cosmos and study the Sun, planets, asteroids, stars and galaxies. Measurements of basic properties of astronomical objects will be performed. Quantitative analysis of these measurements will enable us to determine such things as the mass of jupiter as well as the ages of stars. The course will cover the following topics:

  • Basic Optical Observational Techniques
    • Finding astronomical objects.
    • Optical Telescope Design.
    • Imaging astronomical objects with a CCD camera.
    • Filters and Photometry.
    • Design and use of spectrographs.
    • Atmospheric effects and limitations.
  • Basic Concepts of Radio Astronomy
    • The electromagnetic spectrum.
    • Radio Spectra, Brightness and Temperature
    • Radio Detectors
    • Properties of Radio Sources (Sun, Jupiter, Galaxy, ET...)

Observing projects will be an integral component of the course. The facilities available include a 10 foot diameter Radio Telescope, one 12" Optical telescope, one 11   and four 10" optical telescopes. Each of the optical telescopes will be equipped with a CCD camera. An SBIG self-guiding spectrograph capable of identifying objects such as quasars is also available . Computer equipment is available to store and analyze the images obtained from each telescope. The observing projects may include, planetary satellite orbits, asteroid photometry, Cepheid variable stars, gaseous nebulae, galactic rotation, color-magnitude diagrams for star clusters. Prerequisites: Algebra. Familiarity with computers. A background in physics would be useful. However an enthusiatic backyard astronomer without these prerequisites would be welcome.
