| Abstract: |
Density waves in the central kpc of galaxies, taking the form of spirals, bars and/or lopsided density distributions are potential actors in the redistribution of angular momentum and thus play an important role in the overall evolution of the central structures, not to mention the possible link with the active/non-active nucleus. I present here kinematic evidence for the presence of such structures using new sets of observations: two-dimensional (OASIS/CFHT) and long-slit (ISAAC/VLT) spectrography of nuclear bars and spirals. I also discuss the importance of m=1 modes in the nuclear regions of galaxies, illustrating this with newly revealed cases and original N-body simulations. |
