Flashlights: More than A Dozen High-Significance Microlensing Events of Extremely Magnified Stars in Galaxies at Redshifts z=0.7-1.5

Patrick L. Kelly, Wenlei Chen, Amruth Alfred +23

Once only accessible in nearby galaxies, we can now study individual stars across much of the observable universe aided by galaxy-cluster gravitational lenses. When a star, compact…

Exotic Image Formation in Strong Gravitational Lensing by Clusters of Galaxies -- II: Uncertainties

Ashish Kumar Meena, Agniva Ghosh, J. S. Bagla +1

Due to the finite amount of observational data, the best-fit parameters corresponding to the reconstructed cluster mass have uncertainties. In turn, these uncertainties affect the…

Gravitational Lensing of Gravitational Waves: Effect of Microlens Population in Lensing Galaxies

Anuj Mishra, Ashish Kumar Meena, Anupreeta More +2

With increasing sensitivities of the current ground-based gravitational-wave (GW) detectors, the prospects of detecting a strongly lensed GW signal are going to be high in the comi…

Exotic Image Formation in Strong Gravitational Lensing by Clusters of Galaxies. I: Cross-Section

A. K. Meena, J. S. Bagla

In a recent paper we have discussed the higher order singularities in gravitational lensing. We have shown that a singularity map, comprising of -lines and unstable (point) si…

Finding Singularities in Gravitational Lensing

Ashish Kumar Meena, J. S. Bagla

The number of strong lens systems is expected to increase significantly in ongoing and upcoming surveys. With an increase in the total number of such systems we expect to discover…

Gravitational lensing of gravitational waves: wave nature and prospects for detection

Ashish Kumar Meena, J S Bagla

We discuss the gravitational lensing of gravitational wave signals from coalescing binaries. We delineate the regime where wave effects are significant from the regime where geomet…
