Simulating Nucleosynthesis and Dynamics of Dwarf Galaxies in the Milky Way Plane of Satellites

ORAL

Abstract

The dwarf galaxies surrounding the Milky Way are a unique environment in which to explore the early evolution and nucleosynthesis in the galaxy. We have utilized the state of the are The Next Generation Illustrus TNG50 simulation to identify Milky Way like galaxies and their satellite systems that most resemble the plane of dwarf satellites of the Milky Way. These simulations evidence a unique dynamical history and associated nucleosynthesis. Our detailed comparison of the simulated abundance suggests the importance of carefully analyzing the history of Type Ia supernovae during their evolution. Implications for nucleosynthesis in early core collapse supernovae a Type Ia supernovae will be discussed.
