Query: The VST Early-type GAlaxy Survey: Exploring the Outskirts and
  Intra-cluster Regions of Galaxies in the Low-surface-brightness Regime   The VST Early-type GAlaxy Survey (VEGAS) is a deep, multi-band (u, g, r, i)
imaging survey, carried out with the 2.6-metre VLT Survey Telescope (VST) at
ESO's Paranal Observatory in Chile. VEGAS combines the wide (1-square-degree)
OmegaCAM imager and long integration times, together with a specially designed
observing strategy. It has proven to be a gold mine for studies of features at
very low surface brightness, down to levels of mu_g~27-30 magnitudes
arcsec^(-2), over 5-8 magnitudes fainter than the dark sky at Paranal. In this
article we highlight the main science results obtained with VEGAS observations
of galaxies across different environments, from dense clusters of galaxies to
unexplored poor groups and in the field.
