Resumen:
We present a detailed study of the internal kinematics and the physical properties of the nebular material in four star-forming knots of the galaxy Haro 15. Using long-slit and echelle spectroscopy, we study the physical conditions, chemical abundances, reddening and ionization structure, from the global emission and for the different kinematical components. As the most intense star-forming regions have shown a peculiar kinematic behavior, we focus our study in their kinematic structure. Using high quality Integral Field Unit (IFU) data from GMOS-South of the Gemini Telescopes, we have mapped the velocity fields and flux distribution from fits to different emission lines. The observed kinematic structure in Haro 15 has shown to be extremely complex, combining an evident rotation around a preferential axis with local deviations in around some star-forming areas.
