Abstract: Cosmological data is typically analysed under the model assumptions of exact spatial homogeneity and isotropy in the space-time description of our Universe. However, such symmetries are in reality broken due to the presence of cosmic structure.
I will present cosmographic strategies for analysing data while remaining agnostic about the form of the metric of space-time and the field equations prescribing it.
I will discuss standardisable objects and redshift drift signals as model-independent probes of the kinematics of our Universe. The developed frameworks allow for consistent analyses of anisotropic features in cosmological data.
