### Content, Learning Outcome and Preconditions

#### Content

- Introduction to the concepts of relativity and covariance
- The equivalence principle. Gravitation. The Einstein’s equation. Newtonian limit.
- The Schwartzschild Metric. Black holes.
- The weak field approximation. Gravitational waves.
- Cosmology: Homogeneity and isotropy, Robertson-Walker metric.

#### Learning Outcome

After participation in the Module the student is able to:

- Understand the origin of gravity as the effect of the curvature of spacetime.
- Describe the classical experimental tests of general relativity: the deflection of light, the precession of perihelia and gravitational redshift.
- Understand the basic physics of black holes.
- Understand the basic properties of gravitational waves.
- Describe the different stages of the expanding Universe and derive the Hubble’s law.
- Uniderstand particle physics in the early, hot Universe

#### Preconditions

No prior knowledge necessary, beyond the admission requirements for the master's degree.

#### Learning and Teaching Methods

This module consists of a lecture and an exercise course.

The lecture is designed for the presentation of the subject, usually by blackboard presentation. The focus resides on theoretical foundations of the field, presentation of methods and simple, illustrative examples. Command of basic methods is deepened and practised through homework problems, which cover important aspects of the field.

In the exercise course the learning content is deepened and exercised using problem examples, developing the analytic skills of the students and their ability to perform calculations. The homework problems are discussed in the exercise by the students themselves under the supervision of a tutor in order to develop the skills to explain a physics problem logically.

### Module Exam

#### Description of exams and course work

There will be a written exam of 180 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.

For example an assignment in the exam might be:

- Calculate the motion of a test particle in curved space-time.
- Derive some of the most important known solutions to the Einstein field equations.
- Compute the emission of gravitational waves of a given source.

Participation in the tutorials is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term. The latter is considered passed if 50% of the points in the homework problems have been achieved.

#### Exam Repetition

The exam may be repeated at the end of the semester.
