    • Mapping the stellar age of the Milky Way bulge with the VVV : II. Deep JK s catalog release based on PSF photometry 

      Surot, F.; Valenti, Elena; Hidalgo, S. L.; Zoccali, M.; Gonzalez, O. A.; Sökmen, E.; Minniti, D.; Rejkuba, M.; Lucas, P. W. (2019-09-01)
      Context. The bulge represents the best compromise between old and massive Galactic components, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way formed and evolved. In addition, ...

    • 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 ...
