Cosmological simulations of Milky Way-sized galaxies

Understand

We introduce a new set of eight Milky Way-sized cosmological simulations performed using the AMR code ART + Hydrodynamics in a LCDM cosmology.

• The set of zoom-in simulations covers present-day virial masses in the 0.83-1.56 x 10^12 msun range and is carried out with our simple but effective deterministic star formation (SF) and ``explosive' stellar feedback prescriptions.
• The work is focused on showing the goodness of the simulated set of ``field' Milky Way-sized galaxies.
• Our results are as follows.
