GALAXY EVOLUTION IN THE PRESENT DAY
New detections of coherent streams and merger remnants in the
Galaxy have reinforced our picture that the Galaxy is not a static place even
at the present day. This continuous process of gravitational interaction and
accretion leaves its signature on the global density and kinematic structure
of the Galaxy, allowing us to unravel the recent history of the Milky Way. With
the right instrumentation, we can apply this close-up view of galaxy interactions
to the interpretation of the kinematics, population content, stellar and dark
matter density profiles of nearby galaxies and groups, shedding important light
on the processes which set the distribution of galaxy properties we observe
today and in the earlier universe.
