The Chemical Evolution of the Milky Way in a Cosmological Context

Galactic and Cosmic Chemical Evolution with Hypernovae

We provide new nucleosynthesis yields depending on metallicity and energy (i.e., (normal supernovae and hypernovae), and show the evolution of heavy element abundances from C to Zn in the solar neighborhood. We then show the chemodynamical simulation of the Milky Way Galaxy and discuss the G-dwarf problem. We finally show the cosmological simulation and discuss the galaxy formation and chemical...

Chemical Evolution of the Stellar and Gaseous Components of Galaxies in Hydrodynamical Cosmological Simulations

We present preliminary results on the effects of mergers on the chemical properties of galactic objects in hierarchical clustering scenarios. We adopt a hydrodynamical chemical code that allows to describe the coupled evolution of dark matter and baryons within a cosmological context. We found that disk-like and spheroid-like objects have distinctive metallicity patterns that may be the result ...

The chemical evolution of the Milky Way : from light to heavy elements

We present results for the chemical evolution of the Milky Way including predictions for elements from Deuterium to Europium. A comparison with the most accurate and recent data allows us to draw important conclusions on stellar nucleosynthesis processes as well as on mechanisms of galaxy formation.

The Chemical Evolution of the Milky Way

The ancient , metal - poor stars at the outskirts of the Milky Way provide a window on the conditions that governed the universe shortly after the Big Bang . of the infant universef

osmologists have created a highly successful model of the universe, in which the cosmic energy budget is dominated by a cosmological constant Λ and cold dark matter. Perhaps more remarkable, observations have enabled the fundamental parameters of the ΛCDM model to be determined with extremely high precision. However, crucial gaps remain in our understanding: We have yet to figure out how and wh...
