Scientific paper

A kinematical analysis of the irregular galaxy NGC 4449 is presented based on the Fabry-Perot interferometer PUMA observations. In NGC 4449 we analyse its global velocity field, HII regions population as well as the SNR population identified on radioastronomy studies. Our first results for NGC 4449 show that the optical velocity field, presents a decreasing gradient in velocity along the optical bar and an anticorrelation with respect to the velocity field of the HI halo.
