GLAMER Part I: A Code for Gravitational Lensing Simulations with Adaptive Mesh Refinement

Understand

A computer code is described for the simulation of gravitational lensing data.

• The code incorporates adaptive mesh refinement in choosing which rays to shoot based on the requirements of the source size, location and surface brightness distribution or to find critical curves/caustics.
• A variety of source surface brightness models are implemented to represent galaxies and quasar emission regions.
• The lensing mass can be represented by point masses (stars), smoothed simulation particles, analytic halo models, pixelized mass maps or any combination of these.
