Class Syllabus

      ASTR 300B is a class studying the physical processes that emit, absorb, and scatter light in the context of the physics of the interstellar medium. In this class you will learn radiative transfer in one dimension, learn the fundamental physics of thermal and non-thermal emission processes in the interstellar medium, and learn the basics of atomic and molecular spectroscopy. Topic we shall cover in this class include: continuum emission processes due to dust emission and absorption, free-free emission, and synchrotron emission; atomic ionization and recombination and electronic bound-bound transitions; statistical mechanics (Boltzmann Equation) and equilibrium; and molecular rotational, vibrational, and electronic transitions. It is expected that you have completed or are currently taking PHYS 331 (E&M I) and PHYS 371 (Quantum Mechanics I). The two reference textbooks for the course are Astrophysics – Decoding the Cosmos by Judith A. Irwin and Physics of the Interstellar and Intergalactic Medium by Bruce Draine. Both books are available as e-books.
