Lightcone Construction for HACC Cosmological Simulations with LANTERN

Understand

This document describes the LANTERN (Lightcone generAtion via sNapshoT intERpolatioN) code module, our current approach for generating lightcones from HACC [5] simulation products.

• In sec.
• 1, we derive the condition which defines all spacetime events that can be seen by an observer at any given time (we parameterize the surface of the observer's past lightcone).
