The VISCACHA survey is an ambitious project that aims to observe deep and spatially resolved photometry of all star clusters in the periphery of the Magellanic Clouds. The need for a few hundred hours of 4-m telescope time, coupled with an adaptive optics module, makes SAM-I at SOAR [1] the perfect setup.

Among the topics where the VISCACHA survey will play an important role are:

• 3D map of the Magellanic Clouds with accurate physical (age, metallicity, reddening, luminosity function,  total mass) and structural (core radius, tidal radius, ellipticity) parameters for all star clusters;
• Age-metallicity relation and radial gradients
• Star cluster formation and dissolution history
• Initial mass function of high- and low-mass clusters
• Extended main-sequence turnoff

... and more. The first paper, accepted by MNRAS [2], (Maia et al., 2019) describes the survey and the full analysis of nine selected clusters. The figure below is taken from this paper.

Central panel: VISCACHA sample, including ∼130 clusters observed through 2015-2017 (red circles). Small black dots correspond to the catalogued objects in the Magellanic System by Bica et al.(2008: MNRAS 389,678). Surrounding panels:V images of selected targets, representing the variety of cluster types in the survey.
