Systematic errors in strong gravitational lensing reconstructions, a numerical simulation perspective
W. Enzi, S. Vegetti, G. Despali +2
We present the analysis of a sample of twenty-four SLACS-like galaxy-galaxy strong gravitational lens systems with a background source and deflectors from the Illustris-1 simulatio…
Flux-ratio anomalies from discs and other baryonic structures in the Illustris simulation
Jen-Wei Hsueh, Giulia Despali, Simona Vegetti +3
The flux ratios in the multiple images of gravitationally lensed quasars can provide evidence for dark matter substructure in the halo of the lensing galaxy if the flux ratios diff…
Discovery of three strongly lensed quasars in the Sloan Digital Sky Survey
Peter R. Williams, Adriano Agnello, Tommaso Treu +12
We present the discovery of 3 quasar lenses in the Sloan Digital Sky Survey (SDSS), selected using two novel photometry-based selection techniques. The J0941+0518 system, with two…
SHARP - IV. An apparent flux ratio anomaly resolved by the edge-on disc in B0712+472
J. -W. Hsueh, L. Oldham, C. Spingola +6
Flux ratio anomalies in quasar lenses can be attributed to dark matter substructure surrounding the lensing galaxy and, thus, used to constrain the substructure mass fraction. Prev…
