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.
