Unveiling the Behavior of the Ionized Gas in Irregular Galaxies
  We present the results of a detailed kinematical and dynamical analysis performed in two highly interesting gas-rich Irregular galaxies (Irrs): IC 1613 and NGC 4449. The analysis has been accomplished by means of optical Fabry-Perot interferometry mapping the Halpha and [SII] lines. The question we addressed in this study is: how does the ionized gas behave -kinematically and dynamically speaking- on global and local scales in gas-rich Irr galaxies?
