Class time: TuTh 8:55-10:10 am in Astr 119
Office hours: Posted near my door. Also whenever my door is open or by appointment.

Useful Texts: I did not assign a text book, since there is not one book that would cover most. You might consider getting the Rybicki and Lightman book since it is a basic useful reference. If you get another book, I would recommend the Lequeux book. I will prepare lecture notes which will be handed out. The web page lists some additional notes, this syllabus, and I will also put occasional links to papers and figures there.

1. Rybicki and Lightman, Radiative Processes in Astrophysics, 1979 (don't know if there is a later version).
This is a good reference for the basics of radiative transfer, line broadening mechanisms, continuum radiation processes including bremsstrahlung and synchrotron. But it does not do anything on specific ISM lines.

2. James Lequeux, The Interstellar Medium, Springer Verlag 2003. I will use this book this semester in preparing some of the notes. I have ordered two copies for the library and will put one on reserve in the reading room when they arrive.

3. Lyman Spitzer, Physical Processes in the Interstellar Medium. Compact, dense, but rather complete in its coverage of the various physical processes. This is the traditional standard, which now may have been replaced by some other books. I will put one of those in the reading room this semester if I can find my second copy.

Other useful books:

4. Osterbrock, Astrophysics and Gaseous Nebulae and Active Galactic Nuclei. Useful for discussion of HII region and PNe spectra, and supernova remnants and of course AGN. The second edition came out with Gary Ferland as the 2nd author. It is a very good book, it has added quite a bit of actual observed data (you could not find a spectrum of an HII region in the original version!), but as an overall ISM book it is too limited. It focuses on optical/IR diagnostics of ionized gas, and in that area it is unsurpassed.

5. Verschuur and Kellermann, Editors, Galactic and Extra-galactic Radio Astronomy. Many useful chapters for ISM related stuff, but obviously limited to radio astronomical applications, and getting a bit dated though still quite useful.

6. Any good book on the Milky Way, e.g. Binney & Merrifield, will have a chapter on the ISM which gives a useful overview of the ISM distribution in our Galaxy.

Grades will be based on:

Homework 40%
Midterms
35%
Final (oral) 25%

GENERAL INFORMATION AND REQUIREMENTS
  1. Homeworks will be about bi-weekly. Collaboration on home works only makes sense after you have tried seriously to do it yourself. Otherwise, you will become dependent on others' contributions, and it will show during the midterm and final exam. 
  2. We will have two midterms, dates TBD in consultation with students. One of these will be in class, the other will be a take home. Both exams will allow you to use your notes. The final exam (no notes or other materials allowed) will be oral, scheduled during finals week. Typically, those last 45 minutes per student.
  3.  Students are encouraged to consult the NMSU policies regarding assistance available for students with disabilities, and other NMSU relevant NMSU policies regarding excused absences, etc.
