Star formation histories of galaxies in our sample determined using STECKMAP, using the MILES SSP model. The SFRs returned by STECKMAP are relative, not absolute, so we show them in units of Gyr⁻¹. The curves are color-coded based on the satellite stellar masses. STECKMAP does not cover lookback times < 0.5 Gyr. The red and blue lines show the exponentially decaying form (SFR ∝ exp(τt)) of SFHs of red (early-type) and blue (late-type) galaxies respectively (Tojeiro et al. 2013).
