Calculations indicate low microlensing rates through NGC1052-DF2 but O(1-10) events per year possible across the sky with LSST monitoring, potentially enabling independent IMF estimates in UDGs.
Calculation predicts ~60 lensed star transients per JWST pointing in the Cosmic Horseshoe, enabling spatial tests of dark matter and constraints on the stellar IMF.
Over 100 caustic-crossing stellar events identified in the Dragon galaxy at z≈0.725 with JWST data yield a stellar luminosity function slope β=2.18 and confirm parity asymmetry.
