MUlti-Phase Particle Integrator

A complete numerical description of galaxy formation in a cosmological environment has still to be developed: the physical processes involved in star formation act on scales (<1 pc) that are too small to be resolved in simulations describing the cosmological environment (> 1 Mpc). So, such processes need to be included in simulations as sub-resolution effective models.

In this framework, we developed MUPPI, a sub-resolution model for star formation and feedback, loosely based on the earlier semi-analytic multi-phase model of the inter-stellar medium (ISM) by Monaco (2004).
