Bar-Driven Fueling of Galactic Nuclei: A 2D View

I briefly discuss evidences for bar-driven gas fueling in the central regions of galaxies, focusing on scales down to about 10 pc. I thus mention the building of inner disks, and the link with resonances, as well as the corresponding kinematic signatures such as σ-drops and counter-rotating nuclear disks as probed via integral-field spectroscopy.
