论文摘要
YMCA（是的，再次，麦哲伦云）和步骤（{SMC时：原型的演变相互作用的晚期型星系）项目是深度G，I光度测量调查与VLT调查望远镜（VST）进行，并专门研究Magellanic系统的郊区。基督教青年会和步骤的主要目标是识别候选恒星簇，并将其人口普查完成到麦哲伦云的最外层地区。我们采用了一种特定的过度搜索技术，并对色幅度图（CMDS）的目视检查来选择最佳候选者并估算其年龄。迄今为止，我们分析了23平方摄氏度的区域。在大型麦哲伦云的郊区中，检测了85名候选候选人，其中16名估计在所谓的“年龄差距”中落入了年龄。我们将这些对象与文献数据一起使用，以深入了解麦哲伦云的形成和相互作用历史。
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 over-density search technique coupled with a visual inspection of the color magnitude diagrams (CMDs) to select the best candidates and estimate their ages. To date, we analysed a region of 23 sq. deg. in the outskirts of the Large Magellanic Cloud, detecting 85 candidate cluster candidates, 16 of which have estimated ages falling in the so called "age gap". We use these objects together with literature data to gain insight into the formation and interaction history of the Magellanic Clouds.
