Abstract or project description

We provide evidence for dark matter in the universe by presenting rotation curve fits to the Andromeda galaxy (M31) by considering six different dark matter density profiles: Core-modified, Burkert, Pseudo-isothermal, Lucky13, Moore and NFW profiles. The best fits for the rotation curves were obtained using a self written code and optimised using the least-squares method. We also utilise gravitational N-body simulations of non-interacting particles for extracting the halo density and comparing the results of the simulations with the ones obtained from the astrophysical data.
