Description

I will present an overview of temporal variability studies of Sgr A, discussing several observables, such as the flux distribution, the SED, the PSD and (higher order) structure functions, and will give an overview of how these are typically modelled in observational studies. A particular focus will be put on the temporal symmetry of Sgr A, which as a new and useful observable for the study of astronmical time series.
