Towards Understanding Dark Matter Structures

MSc thesis defense by Kasper B. Schmidt

One of the biggest mysteries in modern astrophysics is the appearance and characteristics of Dark Matter (DM) structures. Some relations for the DM structures have already been identified, but there is still much to learn about these structures. For instance, what happens if such a DM structure rotates?

I will present how we have tried to answer this question by adding rotation to the relevant equations. The results from this approach are shown to agree well with recent high-resolution N-body simulations. Furthermore, we have investigated how density profiles of DM structures behave in general. We have done this by creating a Monte Carlo code to optimize the relevant parameters. I will present the considerations behind this approach and the results of it.
