Syllabus

Just about every thing we know about astronomical objects comes from our observations of the electromatic radiation that they emit/absorb/scatter. (Though detection of particles - cosmic rays, neutrinos - and gravitational waves will play an increasingly important role.) Thus, an understanding of the physics of these radiation processes is crucial to making progress in astrophysics. This course will focus on continuum emission from classical processes. Line emission will be covered in Radiative Processes II and/or ISM II. Topics to be covered in this course include

Text and Resources

This course will cover most of the first 7 chapters of Radiative Processes in Astrophysics by Rybicki & Lightman (Wiley).

Since this is a common graduate course, there are several versions of lecture notes available. I suggest

Useful background material is found in e.g.,
