Th (2015-05-01)
      We analyse deep images from the VISTA survey of the Magellanic Clouds in the YJKs filters, covering 14 deg2 (10 tiles), split into 120 subregions, and comprising the main body and Wing of the Small Magellanic Cloud (SMC). ...

    • The VMC survey - XVI : Spatial variation of the cluster-formation activity in the innermost regions of the Large Magellanic Cloud
