Interview with Constanze Jahn: a PhD student visiting OKC

Costanze is a PhD student visiting the Oskar Klein Centre for a couple of months. I asked her to tell us a bit more about this experience.

where are you from? What brings you to Stockholm?
In Germany I am working at the ECAP, the Erlangen Centre for Astroparticle Physics, which is part of the university of Erlangen. There I started my PhD in the H.E.S.S. Collaboration in 2009. During my PhD I also wanted to spend some time abroad and as I work in the area of Dark Matter search my supervisor suggested going to Stockholm, which is very prominent in this area. So last year in october, when the H.E.S.S. collaboration meeting took place here at the AlbaNova, I asked if it is possible to visit the OKC for a couple of months. Naturally the answer was yes and I started figuring out the dates and searching for a place to stay. Eventually I arrived here at the beginning of March and will stay until mid of July.

what have you been working on here at OKC? Can you describe your project?
Here at the OKC I’m working on a study for CTA together with Joakim Edsjö and Jan Conrad. The study is about testing, whether supersymmetric dark matter models will be visible for CTA in a certain analysis framework. In this context I’m of course also using DarkSUSY to get the model parameters and especially the gamma-ray fluxes from dark matter annihilation.

what do you think is good for a PhD student about the Oskar Klein Center?
What I really like about the OKC is that you get to know a lot about the different fields of study here. There are nice seminar talks and also meetings, e.g. the dark matter meeting, where you hear about the status of other experiments and not only the one you are working on. I also like the very nice atmoshere and the friendly and helpful people at OKC.

what will you take with you from Sweden when you will be back in Germany?
I think beside the scientific knowledge and experience I gained, I will also take a lot of very nice memories with me and propably the wish to come back to Sweden soon.
