HBT-HERONS

HBT-HERONS (Hierarchical Bound Tracing - Hydro-Enabled Retrieval of Objects in Numerical Simulations) is a new version of the HBT+ history-based subhalo finder. This new version includes new additions to the code:

• Compatibility with SWIFT outputs.
• Improved tracking of subhaloes in hydrodynamical and dark matter-only simulations.
• Better domain decomposition, which was required to run on the large-scale FLAMINGO simulations.

Documentation on how to compile, run and analyse the outputs of HBT-HERONS is available on the official documentation page.
