KINEMATIC PROPERTIES OF STAR CLUSTERS IN M33

摘要

Star clusters provide a unique and powerful probe useful for studying the star formation histories of galaxies. In particular, the ages, metallicities and kinematics of star clusters bear the imprint of the galaxy formation process. M33 is the only nearby late-type spiral galaxy and it provides a notable connection between the cluster populations of earlier-type spirals and the numerous, nearby later.-type dwarf galaxies. GTC/OSIRIS provides us, for the first time, with adequate velocity precision to reach the faint end of the luminosity function and to perform a detailed spectroscopic study. We will present here high velocity precision of faint star clusters using GTC/OSIRIS as well as brighter star clusters using WHT/WYFFOS. In combination with our photometric study as well as structural parameter analysis, we will provide relevant information of the star formation history and evolution of the galaxy.
