Optimization and Quality Assessment of Baryon Pasting for Intracluster Gas using the Borg Cube Simulation

Understand

Synthetic datasets generated from large-volume gravity-only simulations are an important tool in the calibration of cosmological analyses.

• Their creation often requires accurate inference of baryonic observables from the dark matter field.
• We explore the effectiveness of a baryon pasting algorithm in providing precise estimations of three-dimensional gas thermodynamic properties based on gravity-only simulations.
• We use the Borg Cube, a pair of simulations originating from identical initial conditions, with one run evolved as a gravity-only simulation, and the other incorporating non-radiative hydrodynamics.
