Deep VI imaging in outer regions of M33

We present Subaru/Suprime-Cam deep V and I imaging of seven fields in the outer regions of M33. Our aim is to search for stellar structures corresponding to extended HI clouds...本研究利用斯巴鲁（Subaru）望远镜超主相机（Suprime-Cam），获取了三角座星系（M33）外围七个天区的深场V波段与I波段成像数据。本研究的目标为搜寻与延展中性氢（HI）云对应的恒星结构。
