AST4320 – Cosmology and extragalactic astronomy
Schedule, syllabus and examination date
The first part of the course treats galaxies, active galactic nuclei, and galaxy clusters. In the second part theories for the formation of structures in the Universe and methods for observing them are discussed.
After completing this course you should be able to:
- Describe the different types of galaxies and their physical properties. You should know how the rotation curve of the Milky Way is measured, and treat models for galactic stellar populations and dark matter distributions quantitatively.
- Treat models for clusters of galaxies and methods for determining their masses and dark matter distributions.
- Apply Newtonian perturbation theory and understand the evolution of structures in the linear regime, and the statistical methods for describing them.
- Understand the spherical collapse model for structure formation, both qualitatively and quantitatively.
- Describe how gravitational lenses can be used as a tool to study structures in the Universe, and apply them quantitatively in idealized situations.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.
Recommended previous knowledge
Bachelor degree of the Fysikk, astronomi og meteorologi (bachelor's) programme or comparable.
Four hours of lectures and two hours of tutorials each week.
Access to teaching
A student who has completed compulsory instruction and coursework and has had these approved, is not entitled to repeat that instruction and coursework. A student who has been admitted to a course, but who has not completed compulsory instruction and coursework or had these approved, is entitled to repeat that instruction and coursework, depending on available capacity.
A final 3 hour written examination will constitute 50% of the final grade. A mid-term test (home or in classroom) will constitute 30% of the final grade. Towards the end of the semester, students are expected to give a 20-25 minute presentation on a topic of choice (topic list will be provided). The presentation will constitute 20% of the final grade. The final grade is determined by an overall assessment of all the parts. A number of compulsory home exercises without grading may also be given.
Examination support material
All non-communicative resources.
Language of examination
If the course is taught in english, written exams will be given in english.
Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.
Explanations and appeals
Resit an examination
Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.
Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
Special examination arrangements
Application form, deadline and requirements for special examination arrangements.
The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
