Modelling the line-of-sight contribution in substructure lensing

Giulia Despali, Simona Vegetti, Simon D. M. White +2

We investigate how Einstein rings and magnified arcs are affected by small-mass dark-matter haloes placed along the line-of-sight to gravitational lens systems. By comparing the gr…

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…
