GLAMER Part II: Multiple Plane Gravitational Lensing

Understand

We present an extension to multiple planes of the gravitational lensing code {\small GLAMER}.

• The method entails projecting the mass in the observed light-cone onto a discrete number of lens planes and inverse ray-shooting from the image to the source plane.
• The mass on each plane can be represented as halos, simulation particles, a projected mass map extracted form a numerical simulation or any combination of these.
• The image finding is done in a source oriented fashion, where only regions of interest are iteratively refined on an initially coarse image plane grid.
