A binary lensing event toward the LMC: Observations and dark matter implications
Abstract
The MACHO collaboration has recently analyzed 2.1 years of photometric data for about 8.5 million stars in the Large Magellanic Cloud (LMC). This analysis has revealed 8 candidate microlensing events and a total microlensing optical depth of τmeas = 2.9−0.9+1.4 × 10−7. This significantly exceeds the number of events (1.1) and the microlensing optical depth predicted from known stellar populations: τback = 5.4 × 10−8, but it is consistent with …
