Query: The Vista Variables in the Via Lactea (VVV) ESO Public Survey: Current
  Status and First Results   Vista Variables in the Via Lactea (VVV) is an ESO Public Survey that is
performing a variability survey of the Galactic bulge and part of the inner
disk using ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA).
The survey covers 520 deg^2 of sky area in the ZYJHK_S filters, for a total
observing time of 1929 hours, including ~ 10^9 point sources and an estimated ~
10^6 variable stars. Here we describe the current status of the VVV Survey, in
addition to a variety of new results based on VVV data, including light curves
for variable stars, newly discovered globular clusters, open clusters, and
associations. A set of reddening-free indices based on the ZYJHK_S system is
also introduced. Finally, we provide an overview of the VVV Templates Project,
whose main goal is to derive well-defined light curve templates in the near-IR,
for the automated classification of VVV light curves.
