An introduction to the basic physics of astronomy and astrophysics at the graduate level. Principles of energy transfer by radiation. Elements of classical and quantum theory of photon emission; bremsstrahlung, synchrotron radiation. Compton scattering, plasma effects, atomic and molecular electromagnetic transitions. With applications to current research into astrophysical phenomena.
These are a collection of lectures covering topics in an introductory graduate astrophysics course on radiative processes. The subject matter is loosely drawn from [http://adsabs.harvard.edu/abs/1981PEPI...25..432L Radiatve Processes in Astrophysics] by Rybicki & Lightman.
At the end of the semester, each student will develop one new lecture on a subject of their choice to add to this website.
