Schematic scenario for galaxy evolution. Different ellipses refer to different redshifts and galaxy populations, while different evolutionary tracks are plotted between 0.1 and 10 Gyr and refer to SFHs with different timescales and normalized to the total final mass ((τ; log (ℳ_tot/ℳ_⊙)) = (0.1;11.5), (0.3;11.0) [solid red curves]; (0.6;10.7), (1;10.3), (2;10.0) [short dashed green curves]; (5;11), (10;10), (15;9) [long dashed blue curves].
