Content

AIMS OF THE COURSE:

- To realise that observing electromagnetic radiation of celestial bodie is the basic concept to gain information on the cosmos

- To understand the basic concepts in the description of radiative processes relevant in astronomy and astrophysics

- To be able to identify and evaluate the main radiation processes for a wide range of astronomical objects

- To be able to apply the theory of radiation processes in a sample of case studies of realistic astrophysical objects and environments

CONTENT OF THE COURSE:

1. Radiation as our fundamental observable forthe Universe


2. Basic quantities and concepts in description of radiation


3. Radiation transport and equilibrium


4. Classical description of radiation scattering processes


5. Fundamental to describe matter and radiation interactions

6. Bound-bound processes


7. Bound-free and free-free processes

8. Some selected applications:

• cosmology and the cosmic background radiation

• elastic scattering as classical oscillator: Eddington limit, blue sky, and powerful spectral lines

• simple example of spectral line formation

• hydrogen v. calcium in solar atmosphere

• thermal bremstrahlung in photoionised nebula

• limb darkening

• radiative diffusion as a random walk of photons
