Description
In this poster, we track the evolution of cosmic structures and higher level host structures in cosmological simulation as they interact with each other. The structures found in these simulations are made up of groups of dark matter tracer particles called satellite halos and groups of satellite halos called host halos. We implement a multi-level tracking model to track dark matter tracer particles, satellite halos and host halos to understand their behaviour and show how the different structures are formed over time. We also represent the evolution of halos in the form of merger trees for detailed analysis by cosmologists.
