HST Imaging of MEGA Microlensing Candidates in M31

We investigate \(HST\)/ACS and WFPC2 images at the positions of five candidate microlensing events from a large survey of variability in M31 (MEGA). Three closely match unresolved sources, and two produce only flux upper limits. All are confined to regions of the color-magnitude diagram where stella...
