Abstract

Non-axisymmetric potentials induce the formation of some structural components of galaxies such as spiral arms and stellar bars. These kinds of perturbations over axisymmetric potentials affect the dynamics of particles on the disk by changing their orbits, being able to induce deviations in the circular rotation. In this talk I will address on the incidence of bar-like flows in galaxies observed with integral field spectroscopic data (MUSE and MaNGA). I will show that gas and stellar velocity fields of barred galaxies are affected by the bar-potential, and they are better described with elongated orbits instead of pure circular rotation models.
