The only required textbook is Physics of the Interstellar and Intergalactic Medium by Bruce Draine. I would also encourage you to pick up a copy of The Physics of Astrophysics, Volume II: Gas Dynamics , which will be our primary text for the Fluids & Plasmas content at the end of the semester.
I will also draw material as needed from Osterbrock & Ferland, Astrophysics of Gaseous Nebulae and Active Galactic Nuclei and Spitzer, Physical Processes in the Interstellar Medium, and for review of material from PHY 514 Radiative Processes from Rybicki & Lightman, Radiative Processes in Astrophysics and Shu's Volume I: Radiation. Everything listed above beyond the required textbook is on reserve in the physics library.
Here's the official course catalog listing:
"Interstellar Matter. Prerequisite: 750:514, Radiative Processes, or equivalent. Properties of the interstellar and intergalactic media: molecular, neutral atomic, and plasma phases. Interstellar dust, magnetic fields, and cosmic rays. Applications of fluid mechanics: instabilities, shocks, magnetohydrodynamics. Star formation and feedback."
In general, I will try to highlight subjects that are important to areas of current research in extragalactic astrophysics and cosmology (e.g., galaxy formation, the enrichment of the intergalactic medium, and the reionization of the universe).
Schedule Both the sequence of lectures and the assignment due dates are preliminary; I will update them as needed during the course of the semester to reflect topics actually covered.
