Image simulations for gravitational lensing with SkyLens
  We present the latest version of the ray-tracing simulation code Skylens,
which can be used to develop image simulations that reproduce strong lensing
observations by any mass distribution with a high level of realism.
Improvements of the code with respect to previous versions include the
implementation of the multi-lens plane formalism, the use of denoised source
galaxies from the Hubble eXtreme Deep Field, and the simulation of
substructures in lensed arcs and images, based on a morphological analysis of
bright nearby galaxies. Skylens can simulate observations with virtually any
telescope. We present examples of space- and ground-based observations of a
galaxy cluster through the Wide Field Channel on the Advanced Camera for
Surveys of the Hubble Space Telescope, the Near Infrared Camera of the James
Webb Space Telescope, the Wide Field Imager of the Wide Field Infrared Survey
Telescope, the Hyper Suprime Camera of the Subaru telescope, and the Visible
Imaging Channel of the Euclid space mission.
