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.

Observational Gravitational Microlensing

, 2002
Gravitational microlensing is name given to the gravitational deflection of light emitted by a luminous source object by a massive 'lens' object which lies close to the observer-source line-of-sight. This results in an apparent time-dependent brightening

Microlensing of Microlensing: Effects of Random Stars on the Double-Source-Plane Gravitational Lens

Microlensing, the influence of stars within a galactic gravitational lens, has emerged as a powerful probe of compact mass and, through differential magnification, sub-parsec scale sources at cosmological distances.

Testing General Relativity with Binary Lens Microlensing Events

The Astrophysical Journal Letters
Einstein’s General Relativity (GR), which has been precisely tested on galaxy and solar system scales, is still poorly constrained in extremely weak gravitational fields (with dimensionless Newtonian potentials of Φ ∼ 10 ^−8 ). In this Letter, we propose
