Astronomical Spectroscopy

Lecturers:  Steve Crawford (SAAO), Yas Hashimoto (SAAO), Roy Booth(HartRAO)

 

Course Outline:

The physical state of an astrophysical plasma is most commonly diagnosed with the analysis of spectra obtained by ground-based telescopes and space-borne detectors over a broad range of electromagnetic windows. The goals of this lecture series are to  illustrate how spectroscopic data are obtained and reduced, define the physical processes that govern the form of astronomical spectra , and discuss the spectral diagnostics that allow us to formulate a physical picture of distant objects. This will take us on a spectral tour of the universe, from which we can measure e.g. the temperatures, pressures, densities,  dynamics and magnetic fields of the great diversity of astrophysical sources.  This course is split into three sections:  Pratical Spectroscopy, Theoretical Spectroscopy, and Radio Spectroscopy.
