Collision tomography: the progenitor of the Andromeda stellar stream and the metallicity gradient

Using N-body simulations of the interaction between an accreting satellite and M31, we have successfully reproduced observed distribution of the Andromeda stellar stream. We predict the spatial distribution of the metal in the progenitor dwarf galaxy by the comparison with the recent observations an...

Zusammenfassung:Using N-body simulations of the interaction between an accreting satellite and M31, we have successfully reproduced observed distribution of the Andromeda stellar stream. We predict the spatial distribution of the metal in the progenitor dwarf galaxy by the comparison with the recent observations and the simulations.
