Strong Lensing by Binary Galaxies

We study the problem of gravitational lensing by binary galaxies, idealized as two isothermal spheres. In a wide binary, each galaxy possesses individual tangential, nearly astroidal, caus-tics and roundish radial caustics. As the separation of the binary is made smaller, the caustics undergo a sequence of metamorphoses. The first metamorphosis occurs when the tangential caustics merge to form ...

Strong Lensing Reconstruction.

We present a general linear algorithm for measuring the surface mass density 1-kappa from the observable reduced shear g=gamma&solm0;&parl0;1-kappa&parr0; in the strong lensing regime. We show that in general, the observed polarization field can be decomposed into "electric" and "magnetic" components, which have independent and redundant solutions, but orthogonal noise properties. By combining ...

Wormhole and C-field

It is well known that a C-field, generated by a certain source equation leads to interesting changes in the cosmological solutions of Einstein's equations. In this article we present and analyze a simple Lorentzian vacuum wormhole in the presence of C-field. The wormhole is very interesting subject in modern cosmology since Morris and Throne have verified the realistic possibilities of construc...

Cosmography with cluster strong lensing

By stacking an ensemble of strong lensing clusters, we demonstrate the feasibility of placing constraints on the dark energy equation of state. This is achieved by using multiple images of sources at two or more distinct redshift planes. The sample of smooth clusters in our simulations is based on observations of massive clusters and the distribution of background galaxies is constructed using ...

Weak Lensing from Strong Clustering

We investigate the effect of weak gravitational lensing in the limit of small angular scales where projected galaxy clustering is strongly nonlinear. This is the regime likely to be probed by future weak lensing surveys. We use well-motivated hierarchical scaling arguments and the plane-parallel approximation to study multi-point statistical properties of the convergence field. These statistics...
