Leiden Astronomy Bachelor's courses Galaxies and Cosmology and Radiative Processes.
This course introduces the theoretical underpinnings and the observational evidence for modern cosmology.
After you learn what evidence exists for the hot Big Bang model, you study the basics of relativistic cosmology. We then discuss the physical processes occurring in the early universe, such as inflation, Big Bang nucleosynthesis and recombination. Finally, you will study the origin of large-scale structure, and use this to interpret the observations of the Cosmic Microwave Background. During the exercise classes, you will apply the material covered in the lectures in more involved calculations.
This course covers the following topics:
Relativistic cosmology (Friedmann equation, distances, basic parameters)
Thermal history of the Universe
Big Bang nucleosynthesis
Basics of structure formation
Interpretation of the Cosmic Microwave Background
Upon completion of this course you will be able to describe the current cosmological model and the observational evidence supporting this. Moreover, you will be able to make basic calculations and read the scientific literature on the topic.
Upon completion of this course you will be able to:
Explain the basics of the current cosmological model
Use the Friedmann equations to calculate basic quantities in an expanding Universe
Explain the problems with the Big Bang models
Explain how inflation solves the problems with the Big Bang model
Explain the basics of Big Bang nucleosynthesis
Interpret observations of the Cosmic Microwave Background
In this course, you are trained in the following behavior-oriented skills:
Explaining and analyzing complex and non-intuitive concepts
See Astronomy master schedules
Mode of instruction
Written exam: 80%, see the Astromoy master examination schedules
Three homework assignments: 20% (if higher than result of written exam)
Blackboard is not used for this course.
