SUMMARY:Simulating the Evolving Milky Way: From Disk to Halo\, Astrono
 my Colloquium\, Sarah Loebman\, University of MI
DESCRIPTION:The Milky Way is the most observationally accessible galax
 y in our Universe.  In many ways it is also a "typical galaxy\," makin
 g it an important benchmark for studying galaxy formation. For this re
 ason\, uncovering the formation history of the Milky Way is the key go
 al of major ongoing surveys such as APOGEE and Gaia. However\, observa
 tions of the Milky Way span a complex multi-dimensional space which ne
 cessitates sophisticated modeling to interpret. In this talk\, I will 
 highlight some recent achievements utilizing state-of-the-art simulati
 ons to aid in our exploration of the Milky Way's formation and evoluti
 on. In particular\, I will discuss recent APOGEE observations of the M
 ilky Way's disk and the role radial migration has played in redistribu
 ting stars within it. I will also discuss observations and simulations
  of kinematics in the Milky Way's stellar halo\, emphasizing how measu
 rements of kinematic moments hold power for constraining the merger hi
 story of the Milky Way. Finally\, I will discuss a strong prediction o
 f LCDM - that stellar halos are radially anisotropic - and I will high
 light the potential Gaia holds for testing this prediction in the Milk
 y Way.
