Abstract

Stellar and gas kinematics encode valuable information about processes shaping galaxies throughout their evolution. This thesis identifies galaxies in the nearby Universe where stars and gas rotate in misaligned planes and presents an analysis of the physical causes of kinematic misalignments, and of the drivers of misalignment timescales. Focusing on galaxies with aligned stellar-gas rotation, the thesis presents a study of the Tully-Fisher relation for stellar and gas rotation at different radii. Finally, the thesis presents a benchmark computation of the circular velocity and halo mass functions, discussing their implications for our knowledge of baryonic Physics in the nearby Universe.
