Stellar cluster dynamical masses in NGC2903

Gas and star velocity dispersions have been derived for four circumnuclear star-forming regions (CNSFRs) and the nucleus of the spiral galaxy NGC 2903 using high-resolution...本工作利用高分辨率观测数据，针对旋涡星系NGC 2903的4个核周恒星形成区（circumnuclear star-forming regions, CNSFRs）及其核区，推导出了气体与恒星的速度弥散。
