Learning outcomes
At the end of the course, the student will gain a deeper knowledge of the concepts regarding the synchrotron radiation and its relation with other processes of the production of radiation in astrophysics. Various astrophysical bodies will be analysed, ranging from interstellar gas, star formation and end-products, generation of radio jets on various scales, processes at the centre of galaxies and in the intergalactic medium, relativistic particle acceleration and re-accelerating, etc. The student will have advanced knowledge on both classical as well as new topics in radioastronomy, in the general framework of modern astrophysical research. The student will be able to understand and present in a critical manner research papers on arguments discussed during the course.
Course contents
The contents of this course can be summarised as follows:
0. Brief recap of emission mechanisms and plasma effects on e-m wave propagation
1. Radioastronomy: detectors & instumentation
2. The InteStellar Matter (ISM) detected by radioastronomy; HI in spiral galaxies & the rotation curve (& Oort Constants)
3. Molecules in the ISM and their relation to star formation
4. Young stellar objects & maser emission (& mega masers)
5. The Sun and Radio Stars
6. Supernovae and their radio remnants
7. Pulsars
8. Microquasars
9. The Milky Way and SgrA*
10. Emission from normal galaxies, star forming and starburst galaxies. Radio Galaxies. Deep fields & radio source population
11. Radio source Physics and evolution; Radio galaxies, FR-I and FR-II (and FR-0)
12.Clusters of galaxies & the (non-thermal) physics of the intergalactic medium
