Simulation of Structure Formation in the presence of Fuzzy Dark Matter using Gevolution Code 

Supervisor: Ali Akbar Abolhasani

 Abstract: In this thesis, the formation of cosmic structures in the presence of fuzzy dark matter (FDM) is investigated using the Gevolution code. In the FDM model, dark matter is composed of ultralight bosons. In fact, the mentioned bosons are the remnants of a scalar field present in the early universe. Simulations of structure formation in the presence of FDM that have been carried out so far (for example with Gadget and RAMSES) are based on Newtonian gravity, which have a number of limitations. The Gevolution code is an N-Body simulation that, unlike other existing simulations, is based on General Relativity, which can lead to interesting results. In fact, in this simulation, the weak field limit in General Relativity is looked at and metric degrees of freedom are calculated. Other advantages of Gevolution code are higher simulation speed and less hardware limitations. In addition, in this code, a number of theories can be studied.
