Course content:
The purpose of this class is to understand how to connect the physical properties of an astrophysical system to the radiation spectrum it emits and through which we are trying to understand it. To do so, we will study various mechanisms of emission of radiation. Specific course themes include:
Particle distribution laws. Radiative transfer. Blackbody radiation. Einstein coefficients. Radiation from accelerating particles. Bremsstrahlung. Synchrotron radiation. Thompson scattering. Nonthermal particle distributions – fermi acceleration. Inverse Compton scattering. Hadronic interactions. Application: – various radiation mechanisms in active galactic nuclei. Polarization: mathematical description, polarization from scattering, polarization and interstellar dust, polarization of Synchrotron radiation. Line emission: level populations and the Saha equation.
Grading:
20% homework sets. 40% in-class tests. 40% final project. For your final project, you will need to write a 4-page proposal, proposing how to understand any astrophysical system of your choice combining observations with any of the radiation processes we have studied in this class (or their combination).
