Metals in galaxies: Is what we see what we expect?
Research report (imported) 2013 - Max Planck Institute for Astrophysics
For decades, theorists have been faced with a problem: How can we explain the diverse chemical properties seen in different types of galaxies in the nearby Universe? Now, an international team of astrophysicists, led by members of the MPA, have found a single, self-consistent model that can indeed simultaneously reconcile these chemical properties. This model follows the standard hierarchical merging scenario of structure formation, and therefore shows that − at least in this respect − what we see in our Universe is what we expect.
