Strong lensing in the Einstein-Straus solution
Thomas Schucker
TL;DR
This paper investigates strong gravitational lensing within the Einstein-Straus model incorporating a positive cosmological constant, comparing theoretical predictions to actual observations of a specific lensed quasar.
Contribution
It provides a detailed analysis of strong lensing effects in the Einstein-Straus solution with cosmological constant, linking theory to observational data.
Findings
Agreement between theory and observed quasar lensing
Insights into the influence of cosmological constant on lensing
Potential implications for cosmological models
Abstract
We analyse strong lensing in the Einstein-Straus solution with positive cosmological constant. For concreteness we compare the theory to the light deflection of the lensed quasar SDSS J1004+4112.
