Probing the Hubble Sequence through Numerical Simulations
Paul Torrey (MIT Kavli Institute)
In astrophysics, numerical simulations are among the most powerful tools available to probe the non-linear regime of cosmic structure formation. They also provide one of the most powerful test-beds for understanding the impact that hydrodynamics and physical feedback processes have on the evolution of galaxies. In my talk, I will present galaxy formation simulations that couple a novel moving mesh hydrodynamical approach with explicit baryon feedback prescriptions. This results in galaxy formation models that reproduce a wide range of observable constrains including the galaxy stellar mass function, cosmic star formation rate, and galaxy morphological diversity. I will discuss the numerical methods that we¹ve employed, how they vary from traditional methods, why this matters for our understanding of galaxy formation, and what we have learned from these large numerical experiments.
Cette conférence s'adresse à tous, y compris les professeurs, les chercheurs et les étudiants des trois cycles. Le café est servi à partir de 11h30.
