96395 - RADIOASTRONOMY

Conoscenze e abilità da conseguire

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.

Contenuti

The contents of this course can be summarised as follows:
