Descripción
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 VST
SV Team, I will present in this paper the first results on the NGC253
structure by the new NIR VISTA and optical VST images. These data have
emphasized the huge potentiality of the VISTA and VST telescopes to
study the structure of galaxies with a detail and accuracy comparable to
higher class telescopes, i.e. VLT and HST, with the advantage of the
large Field of View (FoV): i) the high angular resolution let to detect
and study the sub-structures towards the nuclear regions; ii) the large
FoV let to ''correlate'' the inner features to the structure of the
outer galaxy disk and to map the surface brightness and colors out to
the very faint outskirts.
