1. Gravitational lensing: Galactic groups and clusters are the largest foreground concentration of matter in the universe that are accountable for the gravitational lensing. However, Lieu and Mitaz have shown that WMAP (Wilkinson Microwave Anisotropy Probe) high resolution observational data of the Cosmic ... [100%] 2023-03-04 [Astronomy] [Cosmology]...
2. Gravitational lensing formalism: In general relativity, a point mass deflects a light ray with impact parameter \displaystyle{ b~ }[/math] by an angle approximately equal to where G is the gravitational constant, M the mass of the deflecting object and c the speed of ...

3. Weak gravitational lensing: According to the theory of general relativity, masses deflect light in a way similar to convex glass lenses. This gravitational lensing effect is astigmatic, giving rise to image distortions. [81%] 2021-12-24 [Physics] [Space-time and gravitation]...
4. Weak gravitational lensing: While the presence of any mass bends the path of light passing near it, this effect rarely produces the giant arcs and multiple images associated with strong gravitational lensing. Most lines of sight in the universe are thoroughly in the ... (Physics) [81%] 2023-08-16 [Gravitational lensing]
5. Strong gravitational lensing: Strong gravitational lensing is a gravitational lensing effect that is strong enough to produce multiple images, arcs, or even Einstein rings. Generally, for strong lensing to occur, the projected lens mass density must be greater than the critical density, that ... (Physics) [81%] 2023-11-26 [Gravitational lensing]
6. Optical Gravitational Lensing Experiment: The Optical Gravitational Lensing Experiment (OGLE) is a Polish astronomical project based at the University of Warsaw that runs a long-term variability sky survey (1992–present). The main goals are the detection and classification of variable stars (pulsating and ... (Astronomy) [70%] 2023-05-08 [Astronomical surveys] [Experiments for dark matter search]...
