Studying the interstellar medium of HII/BCD galaxies using IFU spectroscopy

P. Lagos

Abstract.
In this contribution, I will summarize recent results from GMOS-IFU spectroscopic studies of the physical properties (emission lines, extinction, ionization ratios, density, kinematics) and chemical pattern (O/H, N/H, N/O) of the warm interstellar medium in nearby HII/BCD galaxies. Additionally, using GIRAFFE/ARGUS data, we investigate the properties of young star cluster complexes and their gas kinematics. Although, a possible weak N/H gradient is observed in one case, the available data seem to suggest that the metals from previous star-formation events are well mixed and homogeneously distributed through the optical extent of these starbursting dwarf galaxies. The spatial constancy of the N/O ratio might be attributed to efficient transport and mixing of metals by starburst-driven super-shells.
