Separation of Fornax and the MW as a function of the lookback time. We indicate the time of the MW-M 31 flyby (Banik et al. 2018) that we assume ejected the material forming Fornax. We also indicate our assumed moment of the formation of Fornax, which is the starting point of our simulations, just as the times of the two recent observed peaks of star formation in Fornax (Rusakov et al. 2021). The orbit of Fornax was not tuned to have apocenters at the observed starbursts peaks.
