A search for star clusters in the outskirts of the Large Magellanic Cloud indication of clusters in the age gap. (2020)

Abstract:The YMCA (Yes, Magellanic Clouds Again) and STEP (The SMC in Time: Evolution of a Prototype interacting late-type dwarf galaxy) projects are deep g, i photometric surveys carried out with the VLT Survey Telescope (VST) and devoted to study the outskirts of the Magellanic System. A main goal of YMCA and STEP is to identify candidate stellar clusters and complete their census out to the outermost regions of the Magellanic Clouds. We adopted a specific overdensity search technique coupled with a visual inspection of the colour-magnitude diagrams to select the best candidates and estimate their ages. To date, we analysed a region of 23 square degrees in the outskirts of the Large Magellanic Cloud, detecting 85 candidate cluster candidates, 16 of ...(more)
Abstract: (hide)
The data used in this work were obtained with the VLT Survey Telescope (VST) The telescope is equipped with OmegaCAM, a camera with a field-of-view of 1x1deg^2^. The camera is a mosaic of 32-CCD, 16000x16000 detectors with a pixel scale of 0.214-arcsec/pix. For each of the 85 SCs we report: equatorial coordinates, radius, age, reddening, metallicity, apparent and absolute magnitude in the g-band, the tile where the SC in question resides and a flag assessing the reliability of each SC.
