Resumo
In this talk, I summarize the results of our optical integral field spectroscopic observations in a sample of compact and low luminosity HII galaxies. Observations with GMOS-IFU on GEMINI-South in combination with high spatial resolution near-IR images allowed us to make a detailed picture of the interplay between the ISM and the star formation activity in these galaxies. We created and analyzed maps of spatially distributed emission lines and properties of the ISM (ionization indicators, abundances, extinction, kinematics). I also address the question that not all starbursts require an external trigger such as a galaxy-galaxy encounter, as it seems to be the case for a fraction of low luminosity HII galaxies.
