Description
In this talk, I will discuss the chemical evolution of Milky Way-like galaxies with zoomed-in cosmological simulations including long-term radioactive elements. The simulated galaxies considered here are representative of MW-like galaxies according to a range of properties, that include morphology, masses, star formation rate, distribution of chemical abundances. Our simulations have already been tested to reproduce the chemical evolution of α-elements and dust evolution in MW-like galaxies. In this work, we have extended the chemical evolution network of our simulations in order to account also for 40K, and Eu, Th and U. We will then show the predicted abundance patterns for various chemical elements, including long-term radioactive elements. We will also show the distribution maps of radioactive elements across the simulated MW-like galaxies. Finally, we will couple the outputs of our simulations with a mineralogy code to study the potential statistics of Earth-like habitable planets in the Milky Way, thus putting constraints on the Galactic habitable zone.
