Course content

This course provides an overview of radio and microwave astronomy and observations in modern cosmology. It provides thorough training in Bayesian component separation with cosmological applications, emphasizing observations of the cosmic background radiation.

Learning outcome

After completing this course you:

  • will have basic knowledge of the physical processes of radio and microwave radiation from the Milky Way and other galaxies
  • will have knowledge of modern methods for component separation, including Bayesian parameter estimation
  • you will have an overview of relevant data sets for the analysis of cosmic background radiation and other cosmological signals, including COMAP, PASIPHAE, Planck, SPIDER, WMAP, etc.
  • you will know how to use the Commander software package to analyze observations of the cosmic background radiation

Admission to the course

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

A maximum of 15 students per year. If the course has limited capacity, applicants from INTPART institutions in the Global Component Separation Network and students who have the course in their study plan at UiO will be given priority. It will not be possible to enrol in the course after teaching has started.

Overlapping courses


This is an intensive course with lectures and student-active group exercises. The course will last for two weeks with 20 hours of lectures and the rest of the time will consist of project work. During the project work; the student will be required to reproduce a known component separation case. 

Teaching will take place during the last two weeks of August in the autumn semester. It will not be possible to sign up for classes once teaching has started. Students are expected to give an oral presentation of the project work at the end of the second week of the course. Students are also to submit a written report two weeks after completion of the course.

It is compulsory to attend all teaching activities in this course in order to pass the course.


During the course period, the student will prepare a major project assignment, which counts 100 % in the grade assessment. Students can choose whether they want to work on the project individually or in groups. Results from the project assignment will first be presented orally at the end of the course period. Two weeks after completing the course, students must also submit a written report of the project assignment, which will be in the form of a home exam. The final grade is determined by an assessment of the project assignment.

It is compulsory to attend all teaching activities in this course in order to pass the course.

Examination support material

All support material is allowed during work with the project assignment and the home exam.

Language of examination

The examination text is given in English, and you submit your response in English.

Grading scale

Grades are awarded on a pass/fail scale. Read more about the grading system.

Resit an examination

There is no postponed examination in case of illness or the like. If sickness or another valid reason prevents the student from completing the examination, this must be documented with a valid medical certificate or similar before the end of the course. The institute can determine whether a deffered submission and oral presentation can be granted.
