![]() ![]() The data releases are done by VSA in Edinburgh. The final product of the VVV Survey will be a deep near-IR atlas in five passbands and a catalogue of more than a million variable point sources.įor a complete understanding of the variable sources in the Milky Way, the observations will be combined with data from MACHO, OGLE, EROS, VST, Spitzer, HST, Chandra, INTEGRAL, WISE, Fermi lAT, XMM-Newton, GAIA and ALMA.Īs a public survey, the VVV provides data available to the whole community and enable further studies of the history of the Milky Way, its globular cluster evolution and the population census of the Galactic Bulge, as well as the investigation of the star forming regions in the disk. VISTA Telescope's main purpose is in tune with "The Visible & Infrared Survey Telescope for Astronomy" goals, which states: "The purpose of the wide field (1.65° diameter in the IR) survey telescope and camera facility is to perform extensive surveys of the southern skies whose sensitivity is matched to the needs of today’s 8-m class telescopes." The known catalogue by 2010 was about 10^9 point sources, including 33 known globular clusters and ~350 open clusters. since 2010, systematically making the survey area for multiple epochs. With the advanced VISTA 4-metre telescope in Paranal, the VVV Survey has been conducting its 1929 hours of observations over 520 sq. ![]()
