Title: OMEGA-WINGS: First observations of WINGS cluster of galaxies with OmegaCAM@VST
Date: Wednesday, March 6th, 2013
Time: 11:30
Venue: Villa Bazzoni

Abstract I will present the first results of our B and V-band OmegaCAM@VST observations of low-z cluster of galaxies. These observations are part of the multi-wavelength dataset collected by WINGS (WIde-Field Nearby Galaxy-cluster Survey), a wide-field survey of an X-ray selected sample of clusters. The aim of OMEGA-WINGS is to obtain B and V imaging data in the outskirts of all (59) WINGS clusters observable with the VST. We developed an OmegaCAM data-reduction pipeline mainly based on the ESO/MVM data reduction software. I will present a general description of our photometric pipeline, our source extraction and star/galaxy classification procedures. The first results will be presented, and the performances of the pipeline will be discussed. I will finally summarize the lessons we learned during the first year of OmegaCAM observations, the future developments of our survey and its scientific results. Finally, I will also shortly present the WINGS database, which is available to the scientific community as part of the Virtual Observatory thanks to the collaboration with the IA2-team in Trieste.
