Star formation histories for each simulation of the MIRAGE sample. Each panel explores disk orientations for fixed masses respectively given by θ₁_θ₂_κ and Gi_Gj (written on the top right of each panel, see Tables 2 and 3). The last panel shows the SFR of the isolated disk simulations. The curves begin at 100 Myr (see Sect. 5.1). To compare the SFR of merging disks with the SFR of isolated disk per mass unit, the SFR of isolated disks (red dotted lines) have been superimposed on the SFR of merging disks. The black arrow in the merger panels shows the pericentral time t_peri equal to 250 Myr in all the merger simulations. For each galaxy merger, we also display the time of the coalescence of the galactic cores t_c visually determined.
