    • Milky Way demographics with the VVV survey III : Evidence for a great dark lane in the 157 million star bulge color-magnitude diagram 

      Minniti, D.; Saito, R.K.; Gonzalez, O. A.; Zoccali, M.; Rejkuba, M.; Alonso-Garciá, J.; Benjamin, R.; Catelan, M.; Dékány, I.; Emerson, J.P.; Hempel, M.; Lucas, P.W.; Schultheis, M. (2014-11)
      The new generation of IR surveys are revealing and quantifying Galactic features that provide an improved 3D interpretation of our own Galaxy. We present an analysis of the global distribution of dust clouds in the bulge ...

A.; Andrews, H.; Motta, V.; Kurtev, R.; Emerson, J.P.; Bidin, C. Moni; Chené, A.-N. (Cambridge University Press, 2014-03-03)
      The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is an ongoing time-series, near-infrared (IR) survey of the Galactic bulge and an adjacent portion of the inner disk, covering 562 square degrees of the sky, ...

    • Strengthening the open cluster distance scale via VVV photometry 

      Majaess, D.; Turner, D.; Moni Bidin, C.; Geisler, D.; Borissova, J.; Minniti, D.; Bonatto, C.; Gieren, W.; Carraro, G.; Kurtev, R.; Mauro, F.; Chené, A.-N.; Forbes, D.; Lucas, P.W.; Dékány, I.; Saito, R.K.; Soto, M. (2012)
      Approximately 14% of known Galactic open clusters possess absolute errors ≤20% as evaluated from n ≥ 3 independent distance estimates, and the statistics for age estimates are markedly worse. That impedes such diverse ...

    • Variable Stars in the Quintuplet stellar cluster with the VVV Survey 

      Molina, C. Navarro; Borissova, J.; Catelan, M.; Alonso-García, J.; Kerins, E.; Kurtev, R.; Lucas, P. W.; Medina, N.; Minniti, D.; Dékány, I. (2016-10-21)
      The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vicinity of the cluster, using the five-year ...

    • VVV DR1: The first data release of the Milky Way bulge and southern plane from the near-infrared ESO public survey VISTA variables in the Vía Láctea 

      Saito, R.K.; Hempel, M.; Minniti, D.; Lucas, P.W.; Rejkuba, M.; Toledo, I.; Gonzalez, O.
