    • The VMC survey - XII : Star cluster candidates in the large magellanic cloud 

      Piatti, Andrés E.; Guandalini, Roald; Ivanov, Valentin D.; Rubele, Stefano; Cioni, M-R.L.; De Grijs, Richard; For, Bi Qing; Clementini, Gisella; Ripepi, Vincenzo; Anders, Peter; Oliveira, Joana M. (2014-10)
      In this work we analyse colour-magnitude diagrams (CMDs) of catalogued star clusters located in the Large Magellanic Cloud (LMC), from a YJKs photometric data set obtained by the Visible and Infrared Survey Telescope for ...

    • The VMC survey - XVII : The proper motions of the Small Magellanic Cloud and the Milky Way globular cluster 47 Tucanae 

      Cioni, M-R.L.; Bekki, K.; Girardi, L.; De Grijs, Richard; Irwin, M.; Ivanov, Valentin D.; Marconi, M.; Oliveira, Joana M.; Piatti, Andrés E.; Ripepi, V.; van Loon, J. Th (2016-01-28)
      In this study we use multi-epoch near-infrared observations from the VISTA survey of the Magellanic Cloud system (VMC) to measure the proper motion of different stellar populations in a tile of 1.5 deg sq. in size in the ...

    • The VMC Survey - XXI. New star cluster candidates discovered from infrared photometry in the Small Magellanic Cloud 

      Piatti, Andrés E.; Ivanov, Valentin D.; Rubele, Stefano; Marconi, Marcella; Ripepi, Vincenzo; Cioni, Maria Rosa L; Oliveira, Joana M.; Bekki, Kenji (2016-07-21)
      We report the first search for new star clusters performed using the VISTA near-infrared YJKs Magellanic Clouds survey (VMC) data sets. We chose a pilot field of ~0.4 deg2 located in the South-west of the Small Magelllanic ...
