Clusters of starburst galaxy NGC4214

The production rate of ionizing photons in young (<=8Myr), unresolved stellar clusters in the nearby irregular galaxy NGC 4214 is probed using multi-wavelength Hubble Space...本研究借助多波段哈勃空间望远镜，对邻近不规则星系NGC 4214中年龄不超过8百万年（≤8 Myr）的未分解恒星团（unresolved stellar clusters）的电离光子（ionizing photons）产率进行了探测。
