Investigating the Binary Source Degeneracy for Wide-orbit Planets

The Astronomical Journal
Wide-orbit planets are particularly sensitive to detection by the Roman Galactic Bulge Time Domain Survey (GBTDS). This study investigates the degeneracy of these events with binary sources, focusing on how observation cadence affects the resolution of ...

Observations of Microlensed Images with Dual-field Interferometry: On-sky Demonstration and Prospects

The Astrophysical Journal
Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especially those of isolated neutron stars and black holes.

Recent Developments in Gravitational Microlensing

, 2008
Twenty-one years after Bohdan's seminal paper launched the field of gravitational microlensing, it has radically diversified from a method narrowly focused on finding dark matter to a very general astronomical tool. Microlensing has now detected 12 planets, including several that are inaccessible by other search methods. It has resolved the surfaces of

Limits on Planetary-mass Primordial Black Holes from the OGLE High-cadence Survey of the Magellanic Clouds

The Astrophysical Journal Letters
Observations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or wide-orbit exoplanets.
