Description: | The cosmic metal distribution remains largely uncertain. While a few studies have touched on the subject, both using observations and theory, the question of where the metals are in the universe remains an open question. I will report the first chemodynamical results of the OverWhelmingly Large Simulations (OWLS) project, examining the metal distribution in galaxies, the ICM, and the IGM. I will characterize the distribution of metals in density-temperature-metallicity phase space at various redshifts, systematically examining the effects of altering the pertinent prescriptions (stellar IMF, cooling, supernova wind strength, numerical resolution, etc.).
The above image shows a 3 Mpc region in one of our simulations, focused on a protocluster at z = 2. Notice the dense filaments of accreting gas as well as the metal outflows into shock-heated intracluster gas. |
