Objectives

The overall objective of this lecture course is to develop in the students an interest in cosmology, communicating to them in a consistent fashion the basic principles as well as the latest developments in this area.

Learning outcomes and competences

After the frequency of this lecture course, students should be able to: understand the fundamental assumptions behind the standard cosmological model; deduce the equations that describe the dynamics of the Universe; describe the observational evidence of the standard cosmological model; understand the successes and limitations of the standard cosmological model; understand the thermodynamic processes most relevant in cosmology, in particular recombination and primordial nucleosynthesis; describe the observational constraints on cosmological parameters and their consequences for the evolution of the Universe; understand the relevance of scalar fields in cosmology, particularly in solving some of the problems of the standard cosmological model; understand the linear and nonlinear evolution of fluctuations in the density of matter in different eras and scales; understand the mechanisms responsible for the anisotropy of the cosmic microwave background and its relation to the large-scale structure of Universe; describe the observational evidence for dark matter and dark energy. This course also aims to develop a wide range of complementary skills in various areas, such as personal and inter-personal organization, written and oral communication, culture in physics and astronomy and the search and selection of bibliography.

Eligibility for exams

There will not be any recording of attendance in the course but we find it to be essencial that the students attend the lectures.

Calculation formula of final grade

The assessment for the Cosmology course consists of a final exam and the resolution of problems. The final classification in this course will be equal to the classification obtained in the final exam plus up to 4 points due to the resolution of problems. To be successful the students must obtain at least 8 points in the grading of the exam. 

Special assessment (TE, DA, ...)

Assessment is the same for all students.

Classification improvement

Exam - second season (época de recurso).
