Detecting Luminous Gravitational Microlenses Using Spectroscopy
S. Mao, J. Reetz, D. L. Lennon
We propose a new method to detect the gravitational lenses in the ongoing microlensing experiments using medium and high resolution spectroscopy (resolution > 6000). Since the radi…

Real-Time Spectroscopy of Gravitational Microlensing Events - Probing the Evolution of the Galactic Bulge
D. Lennon, S. Mao, J. Reetz +3
We describe a real-time spectroscopic program to observe bright gravitational microlensing events toward the Galactic Bulge. The program is carried out using the NTT at ESO. We pre…
