Fredagskollokvium: Mikjel Thorsrud: Inflation with stable anisotropic hair

First I will talk about acceleration in broad terms. Then we will focus on inflation, more specifically, inflation models that violates isotropy, i.e. three dimensional rotational invariance. Although rotational invariance is a well-established feature of low-energy physics such models have received quite a lot of attention the last few years. I will focus on one of the promising models of such type and ask the question: Does the model lead to an acceptable cosmology at late times? Is it consistent with the observed flatness and isotropy of the universe today? What about imprints in the microwave background radiation and in the large scale structure?
