The Microlensing Event Rate and Optical Depth from MOA-II 9 Yr Survey Toward the Galactic Bulge

The Astrophysical Journal
We present measurements of the microlensing optical depth and event rate toward the Galactic bulge using the data set from the 2006 to 2014 MOA-II survey, which covers 22 bulge fields spanning ∼42 deg ^2 between −5°

Automatic Classification of Microlensing Candidates [PDF]

, 2018
It is both exciting and important to look for life beyond our planet. To find signs of life on distant planets, there is a need to search across the vast space that surrounds us and find planets outside our solar system, called exoplanets. Among the many

The Next Generation Microlensing Search: SuperMacho [PDF]

, 2003
Past microlensing experiments such as the MACHO project have discovered the presence of a larger than expected number of microlensing events toward the Large Magellanic Cloud (LMC).

Demagnifying Gravitational Lenses as Probes of Dark Matter Structures and Nonminimal Couplings to Gravity

The Astrophysical Journal Letters
Magnification of total image fluxes is typically considered a defining feature of gravitational microlensing. In contrast, I will show that nonminimal couplings to gravity can generate regions of negative gravitational potential curvature, giving rise to

Exploring Detection Statistics for Microlensing Events

In this research we aim to develop a baseline filter for microlensing events in the timeseries photometry from the BlackGEM imaging survey using a variety of statistical parameters.
