Constraints on feedback models in galaxy formation from their density slope, mass-size and star formation efficiency in EAGLE ; Belgium

State-of-the-art hydrodynamical simulations with improved stellar and AGN feedback can reproduce the cosmic star formation history of the Universe and the galaxy stellar mass function. Hydrodynamic simulations are currently working only above a certain mass and spatial resolutions, however, and physical processes on smaller scales are implemented via analytic prescriptions known as ‘sub-grid physics’. EAGLE suite of hydro-simulations with several galaxy formation scenarios empowers us to systematically explore the impact of varying feedback prescriptions on large representative populations of...
