The aim of the course is to critically discuss the most relevant issues - some of them still open - concerning Modern Cosmology. We will illustrate its state-of-the-art, and the methods - both theoretical and observational - currently used to investigate its properties. We will further provide a coherent vision which starts from the Big Bang and arrives to the formation of the first galaxies.

Type of delivery of the course
The course will be held with in-presence lectures, augmented with further reading on specific topics in the case of the Astrophysics and Cosmology curriculum.Type of evaluation
The exam will consist in the discussion of a chapter chosen from the article "Hosts and Environments: a (large-scale) radio history of AGN and star-forming galaxies" (https://link.springer.com/article/10.1007/s00159-022-00142-1) and then continue with questions on the entire program covered in class
