Series: Astronomy Colloquium
Date: Monday 13-Mar-2017
Time: 15:00-16:00 (3:00-4:00 pm)
Location: CSS 2400
Speaker: Dr. Federico Marinacci (MIT)
Title: Forming realistic galaxies and magnetic fields in cosmological simulations
Cosmological simulations represent the most complete approach to investigate the complex interplay among the physical processes that shape the evolution of galaxies. In my talk I will present state of the art cosmological simulations performed with an advanced, moving-mesh treatment for hydrodynamics, and featuring a cutting-edge implementation of baryonic physics. I will highlight the tremendous progress made by simulations in producing galaxies that are in agreement with key observables. In particular, I will focus on the formation of realistic disk galaxies similar to our own Milky Way, which has notoriously been a difficult problem to solve in the context of LCDM. Going beyond simple hydrodynamics, I will also discuss evolution of magnetic fields on galactic and cosmic scales. Finally, I will describe current developments on the future generation of simulations, also discussing how more detailed comparisons of the simulation results to the observations may help us to build a fully predictive theory of galaxy formation.
Colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer. Lunch will normally be reserved for the speaker to talk to graduate students.
