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

Understand

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.
• We compare the above SFRFs with the results of SPH simulations run with the code {\small{P-GADGET3(XXL)}}.
• We focus on the role of feedback from Active Galactic Nuclei (AGN) and supernovae in form of galactic winds.
