Some of the foremost questions in the field of cosmology concern the nature of dark matter and dark energy, mysterious phenomena thought to comprise the majority of the matter-energy content in our Universe. In order to test models attempting to describe them, we must be able to make predictions with at least the percent-level precision attained by observations.
These are typically computed within a framework of Newtonian gravity, but there may be relativistic signatures missing from these models that could change the interpretation of the fundamental properties of Universe. My most recent work has therefore explored the impact of general relativistic effects on theoretical predictions of cosmological observations.
