Fredagskollokvium: Simulating the Large Scale Structure of the Universe

In the past few decades, simulations of large scale structure have played a key role in cosmology. They are required to calculate theoretical predictions of cosmological models in the nonlinear regime of gravitational collapse, and they have become an invaluable tool for developing and calibrating analysis methods for galaxy surveys. Using examples from my research, I will discuss how we can use simulations to study the formation of the cosmic web, develop tests of gravity, and prepare for future surveys such as Euclid that will push the limits of the accuracy we require of large scale structure simulations.
