Cosmological constant and lensing
Thomas Schucker
TL;DR
This paper recalculates how the cosmological constant influences light bending around a spherical mass, providing new insights without relying on the traditional lens equation, and compares the results to lensing in clusters.
Contribution
It offers a novel calculation method for the cosmological constant's effect on light bending, differing from previous approaches using the lens equation.
Findings
Recalculated light bending effects considering the cosmological constant.
Compared theoretical results with observational data from lensing clusters.
Provided alternative insights into gravitational lensing influenced by dark energy.
Abstract
The effect of the cosmological constant on the curvature of light due to an isolated spherical mass is recalculated without using the lens equation and compared to a lensing cluster.
