13. Course content

Large scale galaxy surveys are the main observational tools to advance cosmology during the coming decade. These surveys determine the three-dimensional distribution of galaxies in the universe and, by measuring distortions of galaxy images due to gravitational lensing, map also the distribution of dark matter. From these distributions and their statistical measures, including 2- and 3-point correlation functions, power spectra and bispectra, the large-scale properties of the universe can be determined. One key question is the nature of dark energy, the cause for the accelerated expansion of the universe. It can be probed by measuring accurately the expansion history of the universe and the gravity-driven growth of large-scale structure. These galaxy surveys include the Dark Energy Survey (DES) and the future space missions Euclid and Roman. Finland (Universities of Helsinki, Turku, Jyväskylä, Oulu, and Aalto University) participates in Euclid. The course PAP352 Galaxy Survey Cosmology focuses on the distribution of galaxies and the course PAP353 Gravitational Lensing on gravitational lensing, especially on weak lensing (shear) surveys.

14. Recommended and required literature

Lecture notes by the lecturer will be provided on the course homepage. In addition, the following books will be useful

H. Mo, F. van den Bosch, and S. White (MBW): Galaxy Formation and Evolution (Cambridge University Press 2010)

15. Activities and teaching methods in support of learning

Four hours of lectures and written problem sets every week. The problem set session will led by the course assistant and there the correct solutions will be discussed and presented.

16. Assessment practices and criteria, grading scale

The homework will be graded and the grade for the course is based on this homework. To pass with grade 1/5 requires 45% of maximum points.

The highest grade 5/5 requires 85%.
