Nowadays, compact sources relatively warm like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei can be investigated at milli-arcsecond scales only with the VLT in its interferometric mode. We propose a spectro-imager, named VSI (VLTI spectro-imager)

We present deep and accurate Near-Infrared (NIR) photometry of the Galactic Globular Cluster (GC) ω Cen. Data were collected using the Multi-Conjugate Adaptive Optics Demonstrator (MAD) on VLT (ESO). The unprecedented quality of the images provided the opportunity to perform accurate photometry in the central crowded regions. Preliminary results

The front-ends of astronomical research are linked to new telescope improvements, like the building of 10 m-class (and probably larger in a near future) telescopes, and instruments with increasingly larger data gathering capabilities. In the current situation is quite common that astronomers are faced with a huge amount of data to handle in order
