Wide-field studies of extragalactic globular clusters
My thesis intends to better understand the extragalactic globular cluster (GC) populations, as a probe to study the galaxy formation scenarios of early-type galaxies. The globular cluster systems of galaxies can be extended up to larger radii than the galaxy light. The study of GC systems within small galactocentric radius can reveal information about the local GC properties but not their global properties. Hence to get a more accurate picture of GC properties, galaxy studies using wide-field imaging is essential. For this, a survey of early-type galaxies of different masses is undertaken using wide-field imaging from Subaru and Canada France Hawaii Telescopes. This work aims to provide new constraints on galaxy formation and evolution from the globular cluster systems.
