A 2D Spectroscopy view of NGC 588

Most of today's stars were formed in high intensity episodes about 7-10 Gyr ago. However, at these redshifts both resolution and dimming effects make it difficult to study in detail the interaction of the gas, dust and newly formed stars. Giant H II regions in very nearby galaxies constitute their best local

counterpart to address such a study. Here, I present an analysis of NGC 588, a GHIIR in M33, based on optical Integral Field Spectroscopy data obtained with PMAS together with IR images from Spitzer. In particular, I will show that the extinction distribution displays a complex structure with three maxima that correlate well with those for the dust emission at 24micron and 8micron. Also, I will put special attention in identifying the areas of the regions that cause the line ratios measured in the integrated spectrum. Finally, given that it is time to write applications for observing time in CAHA I will report about what I have learnt for the new PMAS's CCD during this work in order to help the public to better planify the observational strategy.
