Course Description

The emission, absorption and scattering of radiation by matter with astrophysical applications. Emphasis on basic theory and problem-solving.

Radiative transfer: specific intensity, transfer equation, opacity, diffusion, scattering.
Statistical mechanics of matter and radiation: LTE, level populations, rate equations.
Electrodynamics: Maxwell equations, spectra of radiation, polarization, dipole and multipole radiation, Thompson scattering.
Plasma radiation: bremsstrahlung and synchrotron emission, Compton scattering, EM wave propagation in plasmas.
Atomic and molecular radiation: energy levels, Einstein coefficients, oscillator strengths, line broadening.

Textbooks

Required:: The Physics of Astrophysics Volume I: Radiation by F.H. Shu
Recommended:: Radiative Processes in Astrophysics by G. Rybicki and A. Lightman

Course Grading

Homework 50%
Midterm Exam 20%
Final Exam 30%

There will be one in-class Midterm exam and an in-class Final. Class participation is strongly encouraged. Class attendance is instead required.

Lecture homework

Homework will be assigned every week or every other week. Their due dates will be announced at the time they are assigned. On the due date the students will be expected to turn in their homework in class. The homework turned in will be graded and returned to the students. I will provide solutions and discuss them in class.
