We give an introduction into the observational technique of integral field or 3D spectroscopy. We discuss advantages and drawbacks of this type of observations and highlight a few science projects enabled by this method. In the second part we describe our 3D spectroscopic survey of Blue Compact Dwarf Galaxies. We show preliminary results from data

The Sculptor Galaxy NGC253 is a nearby barred Sc galaxy seen nearly edge-on and it has been the target of the Science Verification (SV) for the new ESO survey telescopes VST and VISTA: SV have been defined by teams of astronomers from ESO and the community, including the Italian National Institute for Astrophysics. On the behalf of the VISTA and

Supergiant Fast X-ray Transients have been recently unveiled as a new class of High Mass X-ray Binaries thanks to the excellent survey capabilities of the INTEGRAL/IBIS instrument. Although there is a general agreement on explaining the behavior of supergiant Fast X-ray Transients as the result of accretion by a compact object from the wind of a

The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quality stellar libraries. The New Generation Stellar Library (NGSL), recently released, represents a significant step towards the improvement of this situation. To prepare
