Ray-tracing through the Millennium Simulation: Born corrections and lens-lens coupling in cosmic shear and galaxy-galaxy lensing
S. Hilbert, J. Hartlap, S. D. M. White +1
(abridged) We study the accuracy of various approximations to cosmic shear and weak galaxy-galaxy lensing and investigate effects of Born corrections and lens-lens coupling. We use…
Very close pairs of Quasi-Stellar Objects
G. Burbidge, F. Hoyle, P. Schneider
It is pointed out that there are now known four very close pairs of QSOs with separations < 5 arcsec and very different redshifts. Several estimates of the probability that they ar…
Steps towards Nonlinear Cluster Inversion Through Gravitational Distortions. II. Generalization of the Kaiser & Squires Method
Carolin Seitz, Peter Schneider
The weak distortions of high-redshift galaxies caused by gravitational light deflection near clusters of galaxies can be used to reconstruct the projected (two-dimensional) surface…
Steps towards Nonlinear Cluster Inversion Through Gravitational Distortions. I. Basic Considerations and Circular Clusters
Peter Schneider, Carolin Seitz
The distortion of images of faint, high-redshift galaxies by light deflection at foreground clusters of galaxies can be used to determine the (projected) mass distribution of the c…
