We present a fast methodology to produce mock observations of the thermal and kinetic Sunyaev–Zel’dovich (SZ) effects based on darkmatter only N-body simulations coupled with the analytic intra-cluster mediummodel. Themethods employ two different approaches: halo-based pasting (HP) and particle-based pasting (PP). The former pastes gas density and pressure onto halos and requires only halo catalogue, and the latter also considers contribution from field particles as well, i.e., particles which…

Baryonic Post-Processing of N-body Simulations, with Application to Fast Radio Bursts

Where the cosmic baryons lie in and around galactic dark matter halos is only weakly constrained. We develop a method to quickly paint on models for their distribution. Our approach uses the
