Core Documentation

“An Introduction to Modern Astrophysics, II ed. - B.W. Carrol, D.A.
Ostlie - Ed. Pearson, Addison Wesley ”

Type of delivery of the course

Lectures are given using the blackboard and by projecting slides. Some exercises are solved.

Type of evaluation

The candidate will choose and address an astrophysical topic by putting it in its astrophysical context, by describing the most relevant astrophysical issues and by showing how the most relevant formulae are obtained. Then the commission will choose two other topics to be addressed by the candidate in a similar way. The level of accuracy, completeness and critical attitude will be evaluated.
