The Prospector-derived SFHs of the 11 LFBOT hosts in our sample. We see a diversity of SFH shapes: five events have clearly rising SFHs (green border) and the rest appear to have had one (yellow border) or several (pink border) star formation bursts in their past have since declined or plateaued in SFR. All hosts are classified as currently star-forming, given the metric discussed in S. Tacchella et al. (2022).
