From VVV Survey
Vista Variables in the Via Lactea (VVV) is a public IR variability survey of the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. It will take 1929 hours, covering ~10^9 point sources within an area of 520 sq deg, including 33 known globular clusters and ~ 350 open clusters. The final products will be a deep IR atlas in 5 passbands and a catalogue of ~106 variable point sources. These will produce a 3-D map of the surveyed region (unlike single-epoch surveys that only give 2-D maps) using well-understood primary distance indicators such as RR Lyrae stars. It will yield important information on the ages of the populations.
Our Team is composed by around 90 astronomers, and the Principal Investigators are Dante Minitti (DAA, PUC) and Philip Lucas (Centre for Astrophysics Research, University of Hertfordshire).
