The Close-up View of Massive Star Clusters and their Gas

这项提议研究了新形成的大质量星团的性质，这些星团被认为类似于我们银河系和许多其他星系历史上很早就形成的大型星团(所谓的球状星团)。该团队将使用最先进的毫米和亚毫米射电望远镜，如阿塔卡马大毫米/亚毫米阵列，获取分子线和尘埃连续谱数据，以调查这些年轻的大质量星系团的恒星形成效率。表征这种效率对于星团的生存能力以及恒星形成将如何在星团附近和整个宿主星系中进行具有重要的影响。该团队对一个年轻的大质量星系团进行的低分辨率初步研究暗示，气体转化为恒星的效率令人惊讶。为了取得进展，将以高角度分辨率和灵敏度研究该星系团和一个类似的星系团，这些高分辨率和灵敏度是最近才能用于南方星系团的。还将对一个偏北星系团进行低分辨率研究，以便在第三个背景下开始探索这一重要主题。国际和平协会将继续她成功的努力，让妇女和其他代表性不足的群体参与她的研究。她还将继续发表公开演讲。

This proposal investigates properties of newly formed massive clusters of stars, which are thought to be analogs of the large star clusters (so-called "globular clusters") that formed very early in the history of our Milky Way Galaxy and many other galaxies. The team will acquire molecular-line and dust-continuum data, using the most advanced millimeter and submillimeter radio telescopes such as the Atacama Large Millimeter/Submillimeter Array, to investigate the star formation efficiency in these young massive clusters. Characterizing this efficiency has important ramifications for a star cluster's survivability, as well as for how star formation will progress near the cluster and throughout its host galaxy. The team's low-resolution pilot study of a young massive cluster hints at a surprisingly efficient conversion of gas into stars. To make progress, that cluster and a similar one will be studied with the high angular resolution and sensitivity that have only recently become available for southerly clusters. A low-resolution study of a northerly cluster will also be undertaken to begin exploring this important topic in a third setting. The PI will continue her successful efforts to involve women and other underrepresented groups in her research. She will also continue to give public talks
