Structure and Dynamics of the Central Regions of Disk Galaxies

In this thesis, we focus on the structural components observed in the central regions of disk galaxies, namely bulges and bars. We aim to better understand the formation and evolution scenarios which could lead to the bulges and bars observed in the nearby universe. This study was performed from an observational point of view, by analyzing either the structural and photometric properties of bulges and bars, their kinematics, and stellar population characteristics.
