B/PS bulges and barlenses from the kinematic viewpoint

Using a set of N-body models with different face-on bar morphology and edge-on B/PS bulges, we reproduce the kinematic features of barred galaxies seen in TIMER data. We focus on a particular case of NGC 7755, match it with our model that displays the barlens morphology and find that due to contamination by non-vertical velocity components, different components of the galaxy falling on the same line of sight and other inclination effects, the line-of-sight velocity distribution stops being a reliable indicator of the vertical density distribution features, such as the presence of the B/PS bulge. In addition, we observe the same ring of negative h4 parameter value minima independently of the presence of the barlens, thus confirming the lack of connection between these two features.
