Generating and Analysing non-Gaussian fields
Supervisor: Elena Sellentin
Non-Gaussian fields commonly occur in cosmology, but there is no formalism to treat them. Cosmological parameters are typically measured by first removing all non-Gaussianity. This research will enable direct extraction of parameters from the non-Gaussian fields. The first focus is on generating highly non-Gaussian fields using a HMC sampler. Once that goal is achieved, sufficient statistics will be extracted to measure parameters directly from the non-Gaussian fields. This should help build a formalis such that in the future highly non-Gaussian fields such as measured in weak-lensing surveys or the cosmic web can be analysed.
