The evolution of the star formation rate function and cosmic star formation rate density of galaxies at $z \sim 1-4$

We investigate the evolution of the galaxy Star Formation Rate Function (SFRF) and Cosmic Star Formation Rate Density (CSFRD) of $z\sim 1-4 $ galaxies, using cosmological Smoothed Particle Hydrodynamic (SPH) simulations and a compilation of UV, IR and H$\alpha$ observations. These tracers represent different populations of galaxies with the IR light being a probe of objects with high star formation rates and dust contents, while UV and H$\alpha$ observations provide a census of low star formation galaxies where mild obscuration occurs...
