PROBING THE MILKY WAY GALAXY THROUGH THICK AND THIN (DISCS AND HALO) WITH THE CORRELATION RADIAL VELOCITIES (CORAVEL) AND THE RADIAL VELOCITY EXPERIMENT (RAVE) SURVEYS

摘要

Within the past decade it is being increasingly recognized that many of the clues to the fundamental problem of galaxy formation in the early Universe are contained in the motions and chemical composition of long-lived stars in our Milky Way galaxy. The growing awareness of the importance of the 'fossil record' in the Milky Way galaxy in constraining galaxy-formation theory is reflected by the increasing number of surveys and missions designed to unravel the formation history of the Galaxy. The RAdial Velocity Experiment (RAVE) is a spectroscopic .
