Dec 5, 2023 · Microlensing 101 Gravitational lensing is an observational effect that occurs because the presence of mass warps the fabric of space-time, sort of like the dent a bowling ball makes when set …

Gravitational microlensing is an astronomical phenomenon caused by the gravitational lens effect. It can be used to detect objects that range from the mass of a planet to the mass of a star, regardless of …

gravitational microlensing, brightening of a star by an object passing between the star and an observer. Since 2004 many extrasolar planets have been found through gravitational microlensing, including …

Jan 2, 2018 · One of the more commonly-used methods for indirectly detecting exoplanets is known as Gravitational Microlensing. Essentially, this method relies on the gravitational force of distant objects …

The Optical Gravitational Lensing Experiment (OGLE), led by Andrzej Udalski of Warsaw University, found the first 3 planets ever detected through microlensing. The international project makes use of …

Oct 8, 2025 · Gravitational microlensing is a powerful technique used in astronomy to detect objects that do not emit their own light, such as planets, black holes, and dark matter. This method relies on the …

Gravitational microlensing relies on chance events where from our viewpoint, one star passes in front of another star. The farther star is usually a bright star, and the near one is normally one we couldn't …

What is microlensing? Gravitational microlensing refers to the apparent brightening of a background source caused by a lensing object located sufficiently close to the line of sight.

Gravitational lensing generally refers to the bending of light from a background source by a foreground massive object. Gravitational microlensing is a special case where multiple lensing events occur from …

Despite its advantages, gravitational lensing presents challenges such as image distortion, dependence on unknown mass distributions, and the unpredictability of microlensing events.
