Resumen:
The most intense star-forming regions in the galaxy Haro 15 show a peculiar kinematic behavior in our high resolution spectra which provided information regarding the motion of the individual knots in the galaxy potential. We focus our study in their kinematic structure with the purpose of distinguishing the presence of different components which could be contributing to the observed widths in the global emission profile. Using high quality Integral Field Unit (IFU) data from GMOS-South of Gemini Telescopes, we mapped the velocity fields and flux distribution from fits to the different emission lines. The observed kinematic structure in Haro15 has shown to be extremely complex, combining an evident rotation around a preferential axis with local deviations in and/or around star-forming regions.
