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 - XVI : Spatial variation of the cluster-formation activity in the innermost regions of the Large Magellanic Cloud
Piatti, Andrés E.; De Grijs, Richard; Ripepi, V.; Ivanov, Valentin D.; Cioni, M-R.L.; Marconi, M.; Rubele, S.; Bekki, K.; For, Bi-Qing (2015-11-21)We present results based on YJKs photometry of star clusters in the Large Magellanic Cloud (LMC), distributed throughout the central part of the galaxy's bar and the 30 Doradus region. We analysed the field-star-decontaminated ... -
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 - XVIII : Radial dependence of the low-mass, 0.57-0.82 Msun stellar mass function in the galactic globular cluster 47 Tucanae
Chaoli, Zhang; Li, Chengyuan; De Grijs, Richard; Bekki, K.; Deng, Licai; Zaggia, S.; Rubele, S.; Piatti, Andrés E.; Cioni, M-R.L.; Emerson, J.P.; For, Bi-Qing; Ripepi, V.; Marconi, Marcella; Ivanov, Valentin D.; Chen, Li (2015-12-14)We use near-infrared observations obtained as part of the Visible and Infrared Survey Telescope for Astronomy (VISTA) Survey of the Magellanic Clouds (VMC), as well as two complementary Hubble Space Telescope (HST) data ... -
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 ...
