Gravitational microlensing

, 2001
The formulation of the Theory of General Relativity and the observational evidence for the expansion of the universe provided the basis for much of the work carried out in the field of cosmology over the past hundred years. Huge volumes of research have been conducted to find reliable values for cosmological parameters and to describe the amount and ...

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.

Single-epoch and Differential Astrometric Microlensing of Quasars

The Astrophysical Journal
We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing).

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

Systematic KMTNet Planetary Anomaly Search. XI. Complete Sample of 2016 Subprime Field Planets

The Astronomical Journal
Following Shin et al. (2023b), which is a part of the “Systematic KMTNet Planetary Anomaly Search” series (i.e., a search for planets in the 2016 KMTNet prime fields), we conduct a systematic search of the 2016 KMTNet subprime fields using a semi-machine-
