Title: The Galactic Bulge Exoplanet Mass Function from High Magnification Microlensing Events

Abstract: The gravitational microlensing planet detection method has two main strengths. It is sensitive to planets down to low masses beyond the snow line, where giant planets can form most efficiently, and it is sensitive to planetary systems in different stellar environments, from the Solar neighborhood to the Galactic bulge. Recent improvements in the capabilities of gravitational microlensing search efforts with the OGLE-IV survey, the Korean Microlensing Telescope Network, and the Las Cumbres Observatory (LCO) Global Telescope Network have significantly improved the microlensing exoplanet discovery rate. The Spitzer and K2 microlensing parallax programs have improved our ability to determine masses and distances for planetary systems in the Galactic disk. However, somewhat by accident, our ability to determine the masses and distances to microlensing planetary systems in the Galactic bulge decreased in recent years. We propose use the rapid high magnification alert capability of the MOA-II survey to take advantage of the rapid alert response capability of the LCO network significantly to increase the discovery rate of planetary systems that can be proven to reside in the Galactic bulge.
