LSD & DMT: Lensing Simulation Device and Dense Matter Treatment


This page provides bacis information and links on the numerical software developed by the research group at the Institute. It comprehends two numerical codes that allow for performing sophisticated calculations of physical processes in the field of strong gravity of highly compact objects such as black holes and neutron stars.
