General Info:

Course Outline:

EM fields (vacuum waves, spectrum, polarization)

Radiative transfer (intensity, absorption, emission, scattering, diffusion)

Special relativity (4-vectors, Lorentz transformation, beaming, relativistic motion)

Moving charges (equation of motion, retarded potentials, Larmor's formula, multipole fields)

Bremsstrahlung (Rutherford scattering, emission spectrum, absorption)

Synchrotron (emission spectrum, absorption, polarization, power-law electrons)

Compton scattering (cross-section, inverse-Compton, repeated scatterings)

Plasma physics (wave modes, propagation, eikonal equation, scattering by turbulent plasma)

Atoms (quantum transitions, H, He, shell model, K-alpha/Auger processes)

Bound-free (opacity, photoionization, recombination, Milne, Saha)
