MACHO Bulge Microlensing: Spectroscopy Needed
Abstract
We discuss the analysis of MACHO bulge microlensing. New results that give a smaller optical depth [τ = (2-3) 10-6] are encouragingly closer to current models of the inner Milky Way. Although hundreds of bulge events are now available and much progress has occurred, there is still a need for spectroscopic characterization of the microlensing events.
