Image Details
Caption: Figure 3.
HST reference images from four fields that contain historical microlensing events. Source stars are labeled with yellow arrows, and lens candidates are labeled with blue arrows. One candidate, OGLE-2013-BLG-0341L (bottom right panel), has been confirmed as the true lens via Keck adaptive optics and Euclid data (N. Rektsini et al. 2026, in preparation).
