    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.

    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....

    VVV Pointed Search for New Galactic Open Clusters
    (2011) Borissova, J.; Kurtev, R.; Peñaloza, F.; Bonatto, C.; Folkes, S. L.; Sale, S. E.; Clarke, J.; Minniti, D.; Catelan, Marcio; Hempel, M.; Toledo, I.; Saito, R.; Ivanov, V.; Chene, A. N.; Geisler, D.; Bica, E.
    We are reporting the discovery of 96 new infrared open clusters and stellar groups, found using in the disk area of the ``VVV-Vista Variables in the Via Lactea'' ESO Large Survey. Our search focused on the directions of known star formation regions, masers, radio and infrared sources....
