BSc Programme in Physics

Content

The course will give an introduction to cosmology; the formation, content and evolution of the universe. The course will give the students a sense of how astrophysics and cosmology build upon concepts from nearly all parts of modern physics. Therefore, throughout there will be a basic introduction to astronomy and the physics required. In addition to standard problem-solving classes, the course will encourage critical thinking, introduce basic computing approaches, and expose the students to the original literature. There will also be several inspirational lectures by recognized scientists.

Learning Outcome

Knowledge:

The goal is that the student achieves a basic understanding of the Big Bang model, including why this is the prevalent theory, an insight into modern cosmological problems such as what is dark matter, what is dark energy, what is the cosmic microwave radiation and how the light elements (particularly hydrogen, deuterium, helium and lithium) were formed. The student will also obtain knowledge from the scientific literature and convey this to other students. The student will learn the basic computing skills to gain increased insight into universe physics.

 

Skills:

The aim of the course is that the student can:

  • Account for the observational basis of cosmology
  • Write up and find simple solutions to the Friedmann equation, the fluid equation and the equation of state
  • Account for what is meant by dark matter and dark energy, as well as account for the evidence for the existence of these components
  • Account for the equation of state for matter, radiation and dark energy
  • Account for how rotation curves of spiral galaxies and the properties of clusters of galaxies give evidence for the existence of dark matter
  • Account for and conduct simple calculations based on the basic physics behind recombination
  • Account for and conduct simple calculations based on the basic physics behind Big Bang nucleosynthesis
  • Read scientific papers and present them to others
  • Use computers to solve problems that cannot be solved analytically

 

Competences:

The course will give the student competences for further studies within cosmology and astrophysics, e.g. through projects or advanced courses. The student will also gain experience in critical thinking about basic physics and gain widely applicable (but basic) computing skills.

See Absalon for course material. The following is an example of suggested course literature:

  • Barbara Ryden: Introduction to Cosmology
It is recommended that the student has followed courses corresponding to the mandatory physics, mathematics and astrophysics of the first two years of the physics BSc with specialisation in astrophysics.
Lectures, problem solving classes, computer exercises, inspirational lectures, presentations of literature studies, discussions.
The course replaces the discontinued courses NFYB16008U Kosmologi and NFYB19002U Cosmology (Astro3)

Type of assessment details
The final grade will be based on completing 6 assignments during the course:
A motivational narrative (5 %), two standard problem solving assignments (counting 10 % and 20 %), two computational projects (one counting 20 % and one 25 %), and one presentation project (counting 20 %). Each of the 6 assignments is assessed and weighted individually, and the final grade is determined based on this.
