cds-question@unistra.frsurveysgalaxiescatalogsphotometrygalaxy-classification-systemsgalaxy-kinematicsWe present the VST Early-type GAlaxy Survey (VEGAS), which is designed to obtain deep multiband photometry in g, r, i, of about one hundred nearby galaxies down to 27.3, 26.8, and 26mag/arcsec^2^ respectively, using the ESO facility VST/OmegaCAM. The goals of the survey are 1) to map the light distribution up to ten effective radii, r_e_; 2) to trace color gradients and surface brightness fluctuation gradients out to a few r_e_ for stellar population characterization; and 3) to obtain a full census of the satellite systems (globular clusters and dwarf galaxies) out to 20% of the galaxy virial radius. The external regions of galaxies retain signatures of the formation and evolution mechanisms that shaped them, and the study of nearby objects enables a detailed analysis of their morphology and interaction features. To clarify the complex variety of formation mechanisms of early-type galaxies (ETGs), wide and deep photometry is the primary observational step, which at the moment has been pursued with only a few dedicated programs. The VEGAS survey has been designated to provide these data for a volume-limited sample with exceptional image quality. In this commissioning photometric paper we illustrate the capabilities of the survey using g- and i-band VST/OmegaCAM images of the nearby galaxy NGC 4472 and of smaller ETGs in the surrounding field. Our surface brightness profiles reach rather faint levels and agree excellently well with previous literature. Genuine new results concern the detection of an intracluster light tail in NGC 4472 and of various substructures at increasing scales. We have also produced extended (g-i) color profiles. The VST/OmegaCAM data that we acquire in the context of the VEGAS survey provide a detailed view of substructures in the optical emission from extended galaxies, which can be as faint as a hundred times below the sky level.2015A&A...581A..10Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/581/A10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/581/A10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/581/A10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/581/A10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/581/A10https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/581/A10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/581/A10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/581/A10/tablec1 (The VEGAS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/581/A10/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/581/A10/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/581/A10/tablec1?GETtext/xml+votable180.050000true21.8495056-71.41327780.0055555555555555566/16401 16406-16407 16459 16468 16475 16481 16496 16501-16503 16593 16605 16640-16642 16645 16647 16649 16651-16652 16663 16667 16670 16675 16677 16685 16693 16699 16726 16738 16742 16745 16762 16769 16774 16778 16788-16789 16800 16813 16819 16833 16837 16839 16850 16858 16870 16884 17169 17179 17183 17259 17263 17267 17348 17351 17365 17367 17456 17582 17594 17606 17626 17660 17928 17933 17939 17944-17945 17947 17959 17967 18007 18023 18029 18040 18042 18082 18087 18105 18113 18116 18119 18124 18128-18129 19463 32909 33310 33329 33335 33412 33414 33423 33455 33474 33480 33516 34820 34837 34845 34882 34891-34892 34898 34904 34918-34919 34936 34958 34980 34999 35005 35025-35026 35033-35034 35050 35059-35061 35068-35069 35071 35240 35338 35403 35424-35425 35427 35433 35435 35522 35524-35525 35532 35535 35537 35550 35557 35559 35567 35570-35571 35573 35579 35595 35599 35610 35622 35634 35644 35747 35752 35754 35777https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/581/A10?format=asciiOpticaldefaultJ/A+A/581/A10/tablec1The VEGAS samplerecnoRecord number assigned by the VizieR team.
