    The Wide View of the Galactic Bulge as seen by the VVV ESO Public Survey
    (2013) Gonzalez, O. A.; Minniti, D.; Lucas, P.; Rejkuba, M.; Zoccali, M.; Valenti, E.; Saito, R.; Emerson, J.; Catelan, Marcio; Toledo, I.; Hempel, M.; Tobar, R.
    The first year of observations of the Galactic Bulge in the Vista Variables in the Via Lactea (VVV), one of ESO's public surveys with the VISTA telescope, have yielded a deep, near-infrared, multi-colour (Z,Y,J,H,Ks) photometric coverage of over 320 square degrees. Results based on this impressive dataset are presented, showing the global properties of the Bulge. Extinction has been mapped using the magnitude and colour of the red clump, revealing a large amount of small-scale structure. This extinction map has been used to de-redden the VVV stellar photometry to study the Bulge morphology from the absolute magnitude of the red clump and to derive photometric metallicities from the colour of red giant branch stars. The VVV survey continues to obtain multi-epoch data to investigate the variable stars in the Bulge.

    We propose a public IR variability survey, named ``Vista Variables in the Vía Láctea'' (VVV), of the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. This would take 1920 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 ∼ 10^6 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. The observations will be combined with data from MACHO, OGLE, EROS, VST, SPITZER, HST, CHANDRA, INTEGRAL, and ALMA for a complete understanding of the variable sources in the inner Milky Way. Several important implications for the history of the Milky Way, for globular cluster evolution, for the population census of the bulge and center, and for pulsation theory would follow from this survey....

    VISTA Variables in the Vía Láctea (VVV) is a public ESO near-IR variability survey aimed at scanning the Milky Way Bulge and an adjacent section of the mid-plane. VVV observations started in October 2009 during ESO science verification. Regular observations for the first year of the survey have been conducted since February 2010 and will cover a total area of 520 square degrees in five passbands and five epochs. Here we address the first results obtained from the VVV Survey as well as the current status of the observations....
