GLOBULAR-CLUSTERS AS MICROLENSING TARGETS

We investigate the possibility of using globular clusters as targets f or microlensing searches. Such searches will be challenging and requir e more powerful telescopes than now employed, but are feasible in the near future. Although expected event rates are low, we show that the w ide variety of lines of sight to globular clusters greatly enhances th e ability to distinguish between halo models using microlensing observ ations as compared with LMC/SMC observations alone, In particular, the halo core radius and power-law exponent can be determined with good a ccuracy.
